World War 3

With this week's events in the Middle East on the table, along with yesterday's shooting down of a passenger plane (with American passengers on it) by Russian forces, is WW3 upon us?

Remember how America got involved in WW2: Germans sank a passenger ship with American passengers on it.

Russia and China already push propaganda and call to overthrow American government:

allow them to gain more power, and this propaganda will turn into military support. I'm surprised this video haven't been removed at all and Google haven't been sued for treason, because Google's servers are hosted on American land.

America have tried to answer back in a similar vein, but China disallows enemy propaganda outright and Russia simply removes anti-establishment videos. And now this silly plane-crash shit, that simple doesn't work. America is truly being run by amateurs.
