If only there were some precedent, for Venezuela's odd refusal of perfectly tainted aid...
"Rejecting aid out of political reasons is not unusual. When the hurricane Katrina in 2005 caused huge damage along the U.S. gulf coast, a number of countries offered humanitarian and technical aid. U.S. President Bush accepted help from some countries, but rejected aid from other ones:
'An offer of aid from the Venezuelan president, Hugo Chávez, which included two mobile hospital units, 120 rescue and first aid experts and 50 tonnes of food, has been rejected, according to the civil rights leader, Jesse Jackson.
'Mr Jackson said the offer from the Venezuelan leader, whom he recently met, included 10 water purification plants, 18 power generation plants and 20 tonnes of bottled water.'
"The U.S. intent to establish a 'humanitarian aid' supply line into Venezuela has a secondary purpose. Such aid is the ideal cover for weapon supplies. In the 1980s designated 'humanitarian aid' flights for Nicaragua were filled with weapons. The orders for those flights were given by Elliot Abrams who is now Trump's special envoy for Venezuela."https://www.moonofalabama.org/2019/02/venezuela-us-aid-gambit-fails-war-plans-lack-support.html#more
