I doubt they would have. They had the chance, because the US military does contract with French and German companies, and they didn't disrupt any supply chain, as far as I know.
DHL is one of the main logistics companies for the US Military, and they are owned by the German Gov't.
History lesson
We needed A1E in Thailand for down airman mission 65-71
and France had about 50 A1E they did not need--Would they help
us--NO, damm NO--not nice about it
Remember History ,Let not repeat
PS was DHL low bidder--I wonder WHY!!
NEVER TRUST THE FRANCE!!!!
The difference is that the US can quickly switch to another carrier in case of problems. Not so easy when you have the infrastructure involved with aircraft.
On one hand I like the idea, because it essentially means that the European taxpayers would be subsidizing our military, since their taxes went into the subsidies that lowered our cost for the aircraft. On the other hand, bidding should be done with fair competition, and one of the bidders being subsidized isn't fair.
