One of the pressures on hold-out governments, like Germany, to supply the Ukrainians is market driven.

Who ever can get the Ukrainians to adopt their obsolete equipment (and get trained on it, with units, logistics, and command structures organized around it) will be the first in line to sell their advanced equipment when the Ukrainians finally move to NATO standards.

In the words of Tom Lehrer’s “Old Dope Peddler”:
“He gives the kids free samples,
because he knows full well,
That today’s young innocent faces,
Will be tomorrow’s clientele”

Germany’s defense contractor Rheinmetall is offering to deliver Leopard 1A5 main battle tanks to Ukraine within six weeks. https://t.co/5DTKPidt2m h/t @AlexLuck9 @marceldirsus
