The FBI warns that the killing of 30,000 Palestinians in Gaza is likely to radicalize many American Muslims and cause a big increase in the threat of terrorism in the US.

This is a reason why it would be to America's advantage to make Israel stop its atrocities in Gaza. But I think the moral reason, that we all have a duty to prevent atrocities, is the most important reason.

I call into question the validity of classifying "homegrown violent extremists" as a "foreign" terrorist threat. It seems to me that nothing can be both "homegrown" and "foreign" at once. But that is a minor detail, not part of the substance of the matter.
