It won t happen anything serious from US part, US cannot enter, they have been warned by Iran, and Russia (this one more prudently ,but give the warning anyways). China and North Korea are on the basket also.
We will see this days, but the best can happen is US reigns in Israel and prohibits Israel to invade Gaza, if not, we are in WW3,not joking.
US carriers does not impresse any country with serious missile forces.
This is a decisive moment, players are serious in their bet, i think US must reign in Israel and work for peace,seriously, if today there is not war, and event like this will repeat in one year or so... players will be even stronger....this is a vicious equation of force.
US must realize this time, they play with their hegemony and if they make pressure other countries would be forced to be hostile to them,in addition.
