This may be the very BEST moment for Russia, China, Iran, etc., to move against the USA while we have a VERY weak president that Americans despise. LOL, time will tell.
Russia, China, Iran.etc are not stupid enough to attack the US. An initial attack will come from the US only. But I don't think that Obama will initiate such an adventure. Let's wait for Hillary.
China gets money/resources from both Russia and the US, war may not be in their interest. Full list of Chinese war involvement here
