The people who HATE America are the same who hate Democracy in General, who hate the French or the Germans too....the only thing is America is a more symbolic target
As far as countries uniting to take the US down, I can name a few but they are not the one one may think of.
The French and the Germans, for example, have had their share of historical disagreements with the US of A but are still strong allies in the "democratic-christian--caucasianish" camp.
Just take a look at Afghanistan if you doubt it!
The fact that they did not agree with the Iraqi mess is another story that has nothing to do with who they would eventually side with if America were to be attacked.
China, North Korea and Russia....what is new there? The European cold war format is over.....not the whole ideology behind it!
Non democratic Arab and African countries...nothing new there either! They want our money, they get it, they blame us for everything and they hate us!
As far as America rotting from inside, it is just a matter of perspective: for some, what I have seen described as rotten or decadence in some previous posts, is considered as progress....go figure :lol:
I do believe that built in, in any democracic system, is the rot that will take it down because men are lazy bums: they want it all without paying a price for it...
It looks like the more freedom we get, the more "reptilian" we get: the "reptilian" brain takes over and we feel entitled to unbridled basic urges...whatever...
Middle class America is still forming the (for now silent) majority with common sense and shared values...the same goes in all democracies of the world, all the dictatorship of the minorities. Eventually, it is going to be up to the fed up hard working middle class (rep & dem alike) to reclaim the streets, the forums, media and ballot boxes from hyper-active and agenda focused minority groups of all kind.
If that does not work....who knows what could come?

But certainly not an invasion of continental USA...
