the ENTIRE east bloc still has a shitty economy.
I think it,s more likely that N Korea attack then Russia.
PS
the USA has more firepower then Russia meaning that it,s suicide if Russia were to attack the USA.
Not suicide, mutually assured destruction. Russia may have less firepower, but the USA has less land Russia would have to nuke, so it sort of balances out.
Back during The Cold War you might have been right.
Nowadays Russia would get pimp slapped. The bottom line is that MAD made an invasion impossible during the cold war, one of the things that maintained MAD was a treaty that neither side would develop missle interception technologies, this is why things like STAR WARS were so contreversial and never really got online like originally conceived. After the end of The Cold War however when the USSR collapsed the US went on to develop anti-missle technologies, some of which we demonstrated during The War On Terror. Most of our current interception systems being based on ground batteries, using planes, or perhaps most importantly on boats and submarines. While it happened years ago there was some serious crap between the US and Russia because Russia felt the US was in violation of treaties even if the USSR with whom the treaties were signed no longer existed. These kinds of systems were also a key point during the recent incident with Georgia, which spilled over into the EU with Russia cutting off the oil. They threatened poland because the US has a missle interception base there which does a lot to hem Russia's missle projection capability in.
Right now the most viable group, though still a long shot, to be able to invade the US is China. The current arms race right now is based more around anti-missle technologies and conventional weapons. China has developed these ground based laser systems (do a search for China, Satellite, Lasers) that can track and blind US satellites as far feteched as that sounds, they have been demonstrating them since around 2006. The bottom line is that the US can shoot down missles, but China can blind the orbital systems that the US uses to aim missles at extreme range. This means that any war between the US and China would require WMD to be brought in at relatively close range to be deployed. China has also been building up it's naval forces... at one point they could not project their forces, but they are gaining an increasing abillity to do so. Things like their "Yuan Class" submarine are also pretty impressive and represent a genuine threat to american ships as well as security for any transports they might deploy carrying soldiers.
Of course to be honest, the odds of fighting on US soil are minimal unless we're dealing with the very, very end of a losing battle. The US maintains a huge naval base in Japan as a foothold into Asia (which has a lot of people in the region alarmed... we pretty much have Japan under military occupation to use it as a military base, but diplomatically we don't say so). Really in a war between China and the US their back yard is liable to be the first front of the war, acting as a "tripwire" if nothing else. Then China has to get accross the world to get to us. If a war with China starts they are most likely to try and colonize Europe, leading to most of the fighting there, and if the war ever hits US soil it will mean that there have been years of constant fighting and they have established the beach heads there they would need to get here. China has allies in the region (they trade with Cuba) but no major military bases they can support to get them to the US. A point to consider about the US is that our navy isn't so powerful just because our ships and subs are awesome (which they are) but because we have pretty much the best sea based infrastructure ever, we own/control/occupy all these little islands all over the world and literally have bases we can use to support our ships anywhere on the globe, there are nations with competitive naval prescences but ours is still the best, and really China doesn't have anything like that... yet, because they are relatively new to the modern navy game.
The US has the good fortune of being seperated by oceans from any of the major civilizations that could threaten us. The only countries that could forseeably engage us on US soil are second and third world countries from south and central America, and most of them would wind up having to get through Mexico first which acts as quite the buffer. If Mexico joined in we're still looking at a situation where nobody down there has the firepower to be anything but an annoyance in the big picture, I mean sure they would do damage and kill a lot of people, but as soon as the US got moving we'd pretty much swat them like a gnat.
Right now our biggest threat on American soil is from our southern border, not so much in terms of military force, but because of terrorist infiltration. One concern we have is that Muslims will come into Mexico/South-Central America with far looser border control to people getting in and then sneak up into the US with illegal immigrants. Due to a similar, though not identical apperance, especially to an American eye a lot of them could pass as Mexicans especially if they learn to speak spanish and blend into those communities. Given the way drug dealers and such use those same tunnels under the border and such, it would be relatively simple for Muslim terrorists to say enter into Mexico, obtain guns from criminal and anti-US elements, enter the US and start shooting things up. One of our major concerns has not been so much 9/11 attacks but the damage that could be done by what amount to cells of terrorists engaging in gueriella warfare. I suppose you could see that extended into an army in theory... but it's not bloody likely, and it couldn't "invade" in a traditional sense and hold anything because if ever engaged seriously it would be wiped out without support... I mean even if you could miraculously get 10-20,000 terrorists here and arm them with AKs and Uzis operating on that scale they would do damage but probably get demolished by the national guard.
So in short... no, I couldn't see it happening. You'd really have to mess up, the US would literally have to go so left-wing crazy that we refused to acknowlege a military force rolling in without resistance.
