I don't get your "you" perspective mate. Is it against China or USA or what? Because if it is either of these countries, both are simply too powerful to go down. USA might be weaker than before but it still packs enough punch for everyone to listen. If you mean China, I am sure you know how fast Chinese are rising.
Listen, practically even under normal circumstances it is impossible to cause a war between the two. Maybe for some local brownie points, Erdogan might go and fire some fancy words at Israel but it will never escalate beyond that. If Turkey enters, then will Syria, Iran and other countries. To avoid nuclear war, US will intervene here and most probably after a few shots and a dozen soldiers dead, the skirmish would stop.
Looking at the volatility of Middle East, even a tiny skirmish can erupt into WW3. Israel is keeping put and so are other countries including Iran which talks more but acts better than what it speaks in terms of sensibility. Turkey is far more rational and other than some political fame, won't go practical on this. Soon after the flotilla incident, Erdogan announced that he would enter with Navy. It has been months and not happened. Because it will not happen. The cost of that war would be too great for all those who are involved. Once it becomes Turkey vs Israel, Iran, Syria, Egypt (new regime) and some other countries of middle east would jump in (doubt the oil sheikhdoms would participate) on Turk side while that would force US to side with Israel. So you see a fight between these two would become a fight between a dozen countries.
ALL this is only talk and not action.
