I loathe the idea of agreeing with Trump and friends, but I do think he is right in pushing for Europe to be more self reliant and battle ready. I distinctly remember Obama pushing Europe to increase defense spending and he got some pledges but I don't think they bore much fruit. Trump's harder stance may have and might be forcing Europe to step up a bit more. Even if so, he still could have handled the whole situation a bit better. Less public belittling and NATO bashing, for example, even if he and this representatives are taking a harder stance behind the scenes.
