I'd go back even further - while it was the UK rather than the US that initiated the action we certainly backed them up when we carved out a chunk of choice territory in the middle of a bunch of recently defeated Arab countries and gave it to the Israelis, who already had a long history of bad blood with their new (and very old) neighbors. A pretty transparent strategy for establish a foothold in the region through a group who would be virtually guaranteed to need our ongoing military support indefinitely. Or how we continue to support them despite the fact that they have been aggressively expanding almost since day one, in direct violation of every treaty they've ever establish with their neighbors.
Or perhaps the many governments around the world that the CIA has had hand in toppling in order to install others more receptive to our interests. Hell, even Saddam Hussein was our man - we toppled the previous democratic government when it looked like they were going to ally with the Russians, and supplied him with much of the training and chemical weapons he used against his populace. We had no problem with his atrocities him until he decided to go independent and stopped jumping whenever we asked.
But at least where global opinion is concerned, it's been our most recent actions in response to (and since) the 9/11 attacks. Fifteen Saudi Arabians, along with one Egyption, one Lebanese, and two men from the United Arab Emirates flew some hijacked planes into some buildings, and we used the event as an excuse to invade Iraq, a nation completely uninvolved in the attacks. And our actions just spiraled downhill from their - you could scarcely have planned a better response to throw the Middle East into turmoil. And everywhere our military goes our corporations just happen to spring up right behind them, siphoning wealth out of the region as fast as possible while we make little more than symbolic attempts to stabilize the region or secure the infrastructure necessary to the health and security of the populace we claimed to be liberating.
