Flight-tracking websites showed dozens of Air Force aerial refueling planes departing from military bases in the United States and heading to Europe on Sunday, fueling speculation of direct U.S. involvement in the widening Israeli-Iranian war.
Military-focused news sites reported that around 30 U.S. Air Force KC-135R and KC-46A tankers were identified by flight-tracking software in what The Times of Israelcalled an “unprecedented mass deployment” to Europe.
I assume most nations of the world taking part is correct. According to Wikipedia WW2 is considered to have started after the invasion of Poland and subsequently UK and France declaring war on Germany, however there were other events beforehand:
Considering how much the world has changed since then with advances in technology etc., I think WW3 will look very different if it happens.
