Even a stopped clock is right twice a day, and Trump is right here.
Israel-Hamas is and has always been a proxy war between US and Iran. Basically, US uses Israel as its tool to do its work in the Middle East of keeping nuclear-armed Islamist theocracies at bay (whether you think this is good work or dirty work is dependent on your political flavour and is irrelevant here: it just is a fact).
With US announcing it will commit troops to support Israel, that proxy war now is close to an actual war.
To PPs scoffing at OP - check your privilege. In fact, we all should. We in Western Europe have enjoyed a long uninterrupted period of peace, safety and wealth since the end of WW2. If we look at the sweep of history, we will see that this is an anomaly, and not our birthright. We have the luxury of taking peace for granted, but that doesn't mean we will always have it, and only the ignorant or arrogant would think otherwise.
