Actually this a masterstroke by US
First it had got Russia busy with the Ukraine and Syrian theatres before it venturing into Chinese theatre. Now China is on it's own vs US-JAPAN-AUS
FOCL You mean to tell me you really believe that this is a masterstroke by USA? Hahaha
Let me try to explain your masterstroke strategy to you.
1. China military is not involved in the Western front or European theatre. USA is. So China military is 100% ready for any war, USA is NOT.
2. Russia is not involved in the Eastern Front or Pacific Arena. USA is. So Russia military is 100% ready for any war, USA is NOT
3. USA is already spreads so thin with deployment in Afghanistan, Iraq, Syria, and now trying to tip-toe into SCS. IMO USA would be lucky not to be humiliated by either China or Russia.
The so-called USA-Japan- Australia alliance is a myth. Without a 100% military ready USA, they will be completely wiped off and furthermore any one who thinks ASEAN, Australia, NZ or even India will joined the military alliance must be a fool. Because no-one else will believe in that. China's military is too powerful and overwhelming for any other nation apart from nuclear power USA. Hence the entire China military strategy is to deal with USA and USA knew that. USA who asked China who is threatening China should look at the mirror.
If USA were to get involved in either of one of the front - Either China or Russia can easily take advantage of the situation and annexed some lands and nations e.g. China annexed more disputed SCS island occupied by others presently or maybe the entire Vietnam itself to be restore as the former province of ANNAM.
Now the question is what can USA do? Stop the war in one of the front to reinforced the other or another lame act of unilateral sanction. Anyone who described this strategy as a MASTERSTROKE must be quite an idiot I am sorry to say. Strategy game is definitely NO NO for him.
