If Donald Trump would like to cut some of the funding going abroad, the first place to cut may be cutting funding that basically gets funneled into terrorist activities.
The amount of corruption in the Palestinian Authority is massive. Money sent to the Fatah often ends up in Hamas hands. However, even money that stays with the Fatah will rarely trickled down to those who really could use a hand.
Most of the funding is basically used to keep the powerful in power and to continue attacks by incentivizing terrorists with high salaries.
This should end.
