You make it sound like it's even trivial to consider that Russia could fund a war, which I think is very naive.
Don't get me wrong, both Russia and China are as much of a threat as any other country in the world, but much like CLS had said; They don't have the stuff to do a full-scale war to come anywhere close to making a dent on North America.
I mean, lets just do the simple math:
- Russia fires on American vessels
- Russia/US declare war
- Russia vs US/NATO Powers/SEATO Powers vs Chinese "wildcard"
Personally speaking, the economic and military power behind the Allied powers would be far too vast for Russia (or China) to come anywhere close to starting something with the United States any time soon. There are reasons why NATO (and the like) exist, to keep their power at bay. While they do have
some of the money to fund a war, it is also important to point out that much of the capital in that country is controlled by outside investment as well. Pull the right strings, and Russia collapses in upon itself.
...Match that with an otherwise moderately equipped and trained military (several outstanding pieces of machinery included), and yeah, its a matter of throwing men at the problem. Something even the Chinese have realized won't work against the United States (see their battle plans over Taiwan)...
Sure, I'd be worried if Russia or China wanted to start a war with us. But they're not stupid enough to do it. I've done a fair bit of research on Russian and Chinese military power in my years to know that the only thing we have to worry about are nuclear weapons, because outside of that, Allied equipment and servicemen are far better off than their Russo-Chinese counterparts.

Which reminds me: Tom Clancy's END WAR comes out soon, should be fun to throw the US/EU against Russia in the game! Or is it US vs EU vs Russia? It gets confusing sometimes...
