Highly improbable.Not even Russia which has a highly developed nuclear arsenal can really afford to piss off the Americans. How can you forget what the Americans did to Bin Laden who was hiding right next to the Pakistan Military Academy in Abbottabad of those ‘Federally Administered Tribal Areas’ of ‘Pakistan’ in a highly covert operation? Does anybody still need any other proof of the American might?? Also, it ought to be mentioned that the White States of America ain’t alone in any kind of conflict against the people of colour in any part of the world.
Of course, the Americans do need to develop a nuclear missile shield but even in its absence, a country has to be absolutely mad to ‘nuke’ the White States of America!
