Ok i have been thinking about this and would like to put down my thoughts on the situation. If you disagree fair comment but this is for discusion not for hurling abuse at each other.
I think that Russia will get Iran and north Korea on their side to fight the Americans. China will in my personal opinion remain neutral.
It is assummed USA will have all the typical allies. But i live in the U.K and if a war is started within the next few months, i think there is a chance the u.k will not get invloved.
My reasoning is, at the moment we have our prime minister Gordan Brown, who is taking some real stick from the u.k public, parliment pretty much everyone. And at the moment it is pretty much inevitable that he wil not be re elected. And he knows this, he has even resorted to calling members of the public and asking them what he can do to become a better prime minister. He knows he messed up big time and is willing to do whatever to stay in power.
So where im going with this is, if the U.K get called to war by the US the one thing that will help Gordan Brown stay in power and win over the public majoirty is by saying no to the US.
Most people in the UK are not afraid of Iraq or Afghanistan because they pose no hgue threat to our public they have no nukes, planes that can reach the uke.t.c Whereas russia pose a huge threat we are within range of all thier missles nukes e.t.c.
By gordan brown saying no to the US. He will win so much public support and win over the people who doubted him as a leader.
Im not sure about other countires but lets assume they participate in the war.
What i think will happen is eventually is USA will really be dominating the war with allies e.t.c. So Russia will opt to lauch nukes. And the US will retaliate
This will destroy both countries especially economically for all the money they have to spend restoring the country. And i beleive US will be the first to give up. Due to the fact they have more to lose. From observing political leaders of the countires e.t.c. I think Russian leaders care less about the population than the US.(Except for any area that is populated by african americans)
So the war will end and becuase of the damage and finacial cost on both sides. Both countries will incur heavy debts and lose much of thier superpower status and China will be officially regognised as the next superpower of the world not the US or Russia.
And China will take advantage of this to expand even furthur and officially take the role of what the US has been holding as :the superpower of the world.
: Im not chinese, and have created this post with no bias towards eithier us or russia, this is what i truly beleive will happen if both countries go to war.
