If Trump expects to be refunded for past aid to Ukraine, the Republicans should refund Canada and Europe for supporting their military operations in Afghanistan.
Canada's involvement in the USA's war in Afghanistan cost us an estimated $18 billion. 158 Canadian soldiers were killed there and another 2000 wounded.
UK spent £32.8 billion and lost 1000+ soldiers.
France, Germany, Italy, Australia, Denmark, Norway - $100's of billions and devastating loss of life.
Pay up, Trump!
