It makes good sense though. International weapons systems integration has massive inertia. If not for that the US would sell a lot less than it does right now, people are not buying because they want to, but because they have to. There has been some progress on integrating more diverse systems but it is slow, the number of people able to do this work is not large outside of the circles where the systems were developed in the first place. But Europe has never really shut down its defense industry, and there has been a massive revival in the last couple of years. It is still ramping up as far as I can see and it will for the foreseeable future. No matter what the outcome of the Trump-Putin summit (I refuse to call it the Ukraine peace summit, just like I wouldn't call the Molotov Ribbentrop meeting the Polish, Latvian and Estonian peace summit).
