A Boring Dystopia

The idea that the actions of world powers are in any way governed by morality is largely a myth. Politicians will try to twist reality and use morality to justify killing people abroad and sometimes morality does align with their interests by coincidence.

But the motivations are always about furthering financial and strategic interests. See the overthrow of the Iranian regime in 1953 to protect oil interests, CIA coups and supporting murderous dictators in countless South American and other countries around the world, the recent Iraq war etc. If a government gets elected somewhere that would threaten our business interests (by taxing or nationalising them for example), we have historically supported bloody coups to remove them and install murderous facist regimes that enable us to keep making money at the cost of countless innocent lives.

Strategic in the sense that we prevent other powers in a region from becoming strong enough to challenge us. Keeping ourselves on top and in charge by keeping others down. Israel is a valuable ally in this regard - they maintain power in the region by keeping others down and keep them focused more on destroying Israel than attacking us.

Palestinian lives aren't important to our governments. They have no real power and there's no real profit to be made from them. Our strategic interest in supporting Israel will always trump any humanitarian interest in preventing genocide.
