To OP, many of the replies are simple phantasms, the people who wrote them could not defend the idea for the life of them. I cannot tell if it's because of lack of knowledge, reasoning ability or general trolling. take this one for example.
My observation is that US is taking full advantage of its WOT campaign to change the ground realities of several regions in its favor to strengthen its hold in those regions or cripple opposition to its interests in such regions.
Iraq; Libya; Egypt; Syria; Al-Qaeda; Hezbollah; Hamas; it seems to be a pattern. The former two are no longer a threat to US interests. With these developments, the process to isolate Iran is also in effect.
After Syria, Iran would be real danger. Iranians should play smart now because their threats will not get them far.
Mr. Zardari made a remark on this end during his last speech in office of presidency; his message was to avert Middle East like crysis in Pakistan by addressing internal rifts and strifes so that foreign powers do not take advantage and cripple the nation.
Libya: went on to fully comply with the west in 2004 [1] , fully abandoned the nuclear program, paid the victims of the Pan-AM sponsored terror attack their money. Cooperation with European states. Practically the dream for the USA and Europe. The situation now is much worse for them, the tribal war has caused instability in oil flow which effect their economy for the worse. The civil war there was caused by their tribal nature, some of the tribes saw a chance to grab for power and took it. It paid off and Gaddafi's tribe lost. Even the bombing campaign was not started by the USA and neither did the USA took a leading part in it.
Iraq: Currently Iraq is a much bigger threat to USA interests in the region then it was in 2003. Now Iraq is heavily influenced by Iran, the main rival of the USA in the region, one simple example is that it allows the Irani planes with military supplies to fly over the country to Syria against USA's wishes.
Syria: So far Western involvement was minimal to non resistant, despite what some conspiracy theorists would tell you it started as genuine demonstrations against a dictatorship, definitely not something uncommon. What was different though was the atmosphere in the Arab world, those were the days after powerful Mubarak lost his seat as well as the ruler of Tunisia, and Gadaffi was hanging in the balance, so they dared to oppose him even after he started massacring the civilians with machine guns, snipers and mortars.
It held long enough till the extremists who just finished their fighting against the USA moved to Syria from Iraq and Afghanistan and the war was fully on it's way. (similar to what happened with the extremists after the Soviet withdrawal from Afghanistan, though it was to the Caucasus, Balkans and the horn of Africa at the time).
I am sorry that it's so long, but it's hard to convey rational is short sentences.
[1] On 19 December 2003, Gaddafi made a surprise announcement about his intentions to dismantle the Libya's WMDs program. Following the announcement, Libya agreed to destruct all of its chemical, nuclear, and biological weapons stockpiles
On 22 January 2004, U.S. military transport planes carried around 55,000 pounds (25,000 kg) of documents and equipments related to Libya's nuclear and ballistic missile programs to the Oak Ridge National Laboratory (ORNL) in Tennessee. On March 2004, over 1,000 additional centrifuge and missile parts were shipped out of Libya.
The chemical weapons program was also actively maintained by Libya under the dictatorship of Muammar Gaddafi, but it was ostensibly decommissioned in the 2000s and early 2010s as Gaddafi sought to normalise relations with the Western world.
