Trump is agreeing to allow Germany to transfer German Patriot systems to Ukraine and then for the US to sell replacement Patriot systems to Germany at the foreign buyers purchase price

Ones we've yet to produce?

As I understand it, President Trump is authorizing Germany to transfer existing German owned Patriot systems already located in Germany to the Ukraine after which the US will sell Germany replacements

The motivation seems to be to get the US out the Ukraine weapons supply chain and hand off the Ukraine support to Germany and the EU, also to have Germany deliver the Patriot systems out of their existing inventory so as not to further deplete US stocks and finally to have Germany pay hard cash for the replacement systems - which are quite pricey for foreign sales, BTW

Smart move on the part of President Trump.
