Estonia has donated anti-tank missiles, howitzers, anti-tank mines, recoilless anti-tank guns, automatic weapons, ammunition, disposable grenade launchers, hand grenades worth >220 million euros.
Pretty incredible when you consider the size of the population of Estonia. If the US were to give at the same rate, you'd be looking at $80B
Considering the difference in economic might, the US would be looking at more like $155B
