I'll go by analyzing how the Declaration of Independence item by item, applies to the present day. Many items of course do not apply, but I'm including the Declaration in whole for completeness.
The unanimous Declaration of the thirteen united States of America,
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.
He has refused his Assent to Laws, the most wholesome and necessary for the public good.
He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.
He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.
He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public Records, for the sole purpose of fatiguing them into compliance with his measures.
This is a reference to royal assent and British colonial bureaucracy, which isn't a good comparison to current US foreign policy.
He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.
He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.
He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands.
He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary powers.
He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries.
The dissolution of legislatures could be compared to regime change, but many items of the quoted list don't quite apply yet.
He has erected a multitude of New Offices, and sent hither swarms of Officers to harrass our people, and eat out their substance.
Most modern armies however don't live off the land, although arguably, one could say that military checkpoints violate this principle.
He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.
It wasn't until 2008 that a status of forces agreement was signed between the US and Iraq. I am unaware of any SOFAs between the US and Afghanistan.
He has affected to render the Military independent of and superior to the Civil power.
Our armies and mercenaries are protected from being prosecuted.
For Quartering large bodies of armed troops among us:
Fortunately, our armed troops don't live off the land, and live in military bases, some of ad-hoc construction.
For protecting them, by a mock Trial, from punishment for any Murders which they should commit on the Inhabitants of these States:
Once again, our armies and mercenaries are protected from being prosecuted, and in some cases the rules of war are violated or ignored. Or to rile your emotion: A pregnant women is being rushed to a hospital, because the car didn't slow down, or didn't slow down fast enough for the checkpoint, the car is shot up. Who would tolerate such a situation?
For cutting off our Trade with all parts of the world:
We are responsible for sanctions against Iraq (killing hundreds of thousands of Iraqis, many children), sanctions against Iran, Syria, North Korea...
For imposing Taxes on us without our Consent:
Our relationship with the nations we invade and occupy are totally different from old fashioned colonialism, fortunately.
For depriving us in many cases, of the benefits of Trial by Jury:
For transporting us beyond Seas to be tried for pretended offences
Guantamano. Secret CIA prisons.
For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies:
For taking away our Charters, abolishing our most valuable Laws, and altering fundamentally the Forms of our Governments:
For context, the first sentence refers to Quebec, whose citizens desired civil law over common law. On the other hand, it is understandable that it would feel quite threatening that a foreign government is changing the governance of a neighboring nation to an ideology that yourself would not desire.
For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.
Martial law really.
He has abdicated Government here, by declaring us out of his Protection and waging War against us.
This has to do with the British colonial relationship with the colonies, stating that the King has renounced his right to govern. I think.
He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people.
Few wars are peaceful.
He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.
Referring to Hessians I believe.
He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.
Impressment, doesn't quite apply to modern circumstances.
He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.
Usually we support and endorse insurrections before invading.
In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.
Nor have We been wanting in attentions to our Brittish brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.
We, therefore, the Representatives of the united States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good People of these Colonies, solemnly publish and declare, That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.
Suffering from the diminishing marginal utility of wealth.
What, exactly, are you referring to, here? Since when has the US had various coups and juntas? And even if it had, how does this invalidate the fact that this country is significantly better off socially, economically, and in just about every possible respect than it was in 1774?
