The Israeli electorate, like most, tends to drift leftward in times of relative security and prosperity, as people begin to forget to what they owe that security and prosperity. That being said, it’s not clear to me that Netanyahu has “lost” any more so than the last election there.
And so the cycle begins again. The libtard brand of socialism is designed to keep the sheeple hovering between complacency and downfall so the ruling class can stay in power. But eventually, they run out of other people's money.
