You don't know what you are talking about. Lets go through it.
1. The government that was supposed to be selling us oil at a cheap price has been a farce, leaving the door wide open for a terrorist organization much, much worse than the ones we even imagined back in '97 to take over. The people we were pretending to liberate are now screwed at a whole new level.
If you are referring to Iraq, that is pretty much pure rubbish. Iraq has been a functioning if troubled democracy since soverignty was restored to its government. There have been a number of elections, and the head of government has changed peacefully. Iraq still controls the majority of its territory, and the region controlled by ISIS is an extention of the territory it controls in Syria. ISIS is not all that different from the Taliban and al Qaida, and it is in essence an offshoot of al Qaida. Al Qaida was active in the 1990s, so your claim there is rubbish as well. The people of Iraq are far better off than they were under Saddam. You're piling rubbish to a whole new level.
2. The politicians who were supposed to be protecting our democracy from threats domestic and abroad have turned out to be so cowardly and corrupt that they can't be bothered to press charges when our secret agencies lie to them about such basic concepts as torturing people or killing American citizens.
Yet more rubbish. The proper members of Congress were briefed regarding enhanced interrogation, and legally those techniques did not constitute torture despite your opinion. American citizens that take up arms with the enemy to make war on the United States can be killed like any other combatant. Maybe you could examine all the trials and warrant serving that occurred on US Civil War battlefields. Hint: that didn't happen. Confederate soldiers were shot down without warrant, arrest, trail, or conviction. That's because it's war, not an action of the criminal justice system. Your confusion on this point results in more rubbish.
3. Said politicians can't muster the courage to back up their so-called liberation efforts with boots on the ground when we're faced with real opposition instead of a puppet that started to bore them.
No "boots on the ground,"
4. And of course, per your argument, they didn't even address the fact that an unpopular secret agency that consistently disregards the legal and constitutional framework of the government funding it pretty much defeats the entire purpose of a democracy, doesn't it?
Unfortuantely you've got it wrong again. The Congress has passed multple laws authorizing NSA activity, and the President has his own Article II powers that don't rely on Congress. The NSA's actions have been authorized, they apparently are within the limits of the Constitution. Since there have been several elections during this period it would seem that democracy in the US continues unimpaired. So, in short, more rubbish.
