He’s financially incentivized to align himself with the political agendas of Israel. This is reflected by his politics and support of Israel with money and weapons, regardless of its genocide in Palestine. He’s stealing taxmoney and giving it to Israel so that they can genocide Palestinians.

All of these things are maintained by humans. There is no perfect structure that can keep everyone “locked” to act in favor of the structure, whether it is through surveillance, bureaucracy or punishments. In any system, a subset of the participants will at some point have leeway to put a small dent to the system. Some systems are more resistant to self-destruction than others, but none are immune to it due to our inherent ability to choose between right and wrong. Therefore, evil systems can always be defeated, and good systems can always fall.
