Fiddy-

There are differing opinions all across the board about the war, what led to the invasion, what's been accomplished/what hasn't, and so on. Best you and I can do is agree not to agree with each other.

As for China invading, that's a completely different scenario. The world knows the U.S. has massive nuclear weapons capabilities, but unlike many countries in the Middle East, we don't run around flaunting our capabilities and threatening genocide on other countries, races, religions, etc. Even China, being the superpower that they are, would still be stupid to ever threaten us with any kind of force... especially with the atrocities that are happening in their country every day that we conveniently ignore. We're the #1 superpower for a reason, we have the ability to obliterate any country within a matter of seconds... luckily, we have no desire to convert the world into 'one big America'. We're not going to run our mouths like a lot of countries in the ME would, because we don't need to. The world knows what we're capable of, and most of the world is grateful that we're not governed by a cruel dictator who desires to see certain countries wiped from the face of the earth.
