> to distract from internal scandals

This is ignoring fifty years of trying to start this war. Even blaming Israel doesn't entirely make sense. A large segment of capital in the US truly wants this war to happen (as foolish as that may seem to rational humans). It is not simply a distraction.

Or to put it another way, the Trump administration is characterized by dozens of scandals of bungled governance, each distracting from the next. Determining which is the "root" thing being distracted from is pointless.
