When politicians are feeling the heat, they start a war and their popularity goes up even if the war is unnecessary or completely ridiculous. Donald Trump, the presidential candidate who promised that he would not take the nation into another Middle Eastern war, did so when he launched a fifty-nine cruise missile barrage against a Syrian Air Base even before he knew for sure what had happened on the ground. It was totally stupid but proved to be popular, even among talking heads and Congressmen, some of whom described his action as "presidential" in the best sense of the word.
It's the same in Israel. For those who have not been following developments there, Prime Minister Benjamin Netanyahu has been under pressure due to an ongoing investigation for corruption. One of the truly great things about Israel is that while they have a lot of corrupt politicians, just like everywhere else, they actually investigate, indict, prosecute, convict and send them to jail. The betting is that Netanyahu will soon be in prison, so he has been responding in the time-honored fashion by threatening his neighbors and hinting at the possibility of increased military action and even war. If there is a war going on, he believes, probably correctly, that no one will want to remove him.
