World War III?

We are not going to beat this enemy unless we get serious about it.
~ Jay Bryant, Real Clear Politics

Newt Gingrich thinks that WWIII has already started. Jay Bryant agrees.

Wherever one stands in answer to this question, it is clear to me that Israel's fight is our own fight. Their mortal enemies are ours. Israel is doing battle for itself and also for the U.S.A.

Hezbollah has always been one of the inevitable fronts in the GWOT, one that the United States would have to face eventually--again. It is the butchering force that murdered our Marines in 1983, and given the chance, it would certainly return to the continued killing of Americans. Our nation owes Israel full gratitude and support for stepping up to Hezbollah's brutal challenge.

Whether or not the current situation is World War III, one thing is certain: it is one war, worldwide.
