A lot of it comes back to your foreign policy. Maybe for every dollar of foreign aid you think they should withhold, they should also withhold probably 10 times that in military spend. Most of the foreign aid is there to either help a geopolitical goal (ie. Egypt, Israel) or to fix a problem they created (ie. Afghanistan, Iraq).

It's sad that a country with such big debt issues prefers to cut back spending on their own people as opposed to cutting back on the overgrown military that they just use to get up to no good around the world.
