Iraq was invaded due to 2 main reasons, control of oil, and to get the US a foothold in the Gulf/middle east area that would allow them to strike anywhere they wish in the future..........
it was not invaded due to there being WMD there, that was simply the excuse used to finally get in there.
USA, like the Egyptians 2,500 years ago, the Romans a few thousand years ago and us Brits a few hundred years ago are simply trying to maintain their empiric control of the world, whereas the Egyptians and Romans did it by and for force, the Brits by technology and for force, the USA do it for money and force. If you deny it then you are being very dumb, the people of the USA want the world to revolve to their ideals, and like all those empires previous, they believe everyone elses ideals are not fit to govern the world so they should.
Personally, i dont care, a war of terrorism will take waaay to long to complete, im likely to have died of old age before it gets to a point i'll be worried, oh sure a few bombs have gone off, so fvcking what? we went thru this 20 years ago with the IRA....lol...its old news......as you saw, did we give a real sh1t? nope, we just wanted to get on with our lives and go to work....lol
oh and if you wonder at any bitterness in my words, simple, twice now we backed the USA in recent history (Afghanistan and Gulf2 Brit troops had to go in first to make sure it was safe for the US troops as you guys didnt have the experience we did in this kind of fighting...lol) and you know what? your president has made it more than clear, despite us backing him against the UN councils wishes, he doesnt feel America owes England any favours........LOL.....now thats sad
