Russia's warfare and United states's  technology -  powerful combination

It won't be s surprise to say that Russia has the best warfare available and it is the world's No 1 Nuclear weapon holder. It has more than 6200 Nuclear war heads which could turn the entire earth into ashes within no time. US on the  other hand has already reached the apex in technology and war fighting. Their sophisticated systems and missiles could put check to any big power in this world. So eventually when these two countries join their hands the combo will be so much powerful. ISIS also possess some sophisticated weapons, recently they have destroyed a Malaysian air liner too. So it is eminent that these two countries have to come forward.
