Want more of something? Subsidize it!
For decades, the US government has subsidized the defense of Israel to the tune of billions of dollars per year.
Is it any wonder, then, that the Israeli government -- and the Arab governments which also receive billions in "peace with Israel tribute" from Uncle Sugar -- always make sure to keep a dire, even existential, threat on low to medium heat to justify the continuation of those subsidies in perpetuity?
Or that they turn up the gas a little bit at key points ... points like, say, the weeks before the inauguration of a new US president?
The point has long since ceased to be whether or not Israel survives or the "Palestinians" get a state, if indeed that ever was the point. The point now is to make damn sure those checks keep getting signed.
Israel isn't going to crush Hamas, because their meal ticket would expire if they did. Hamas isn't going to settle, for the same reason. The show must go on.
High-quality theatre? Perhaps. But it's hell on the extras.
