I don't understand why this is being downvoted. It's not unreasonable to assume that increased militarization, coupled with increased nationalistic sentiment, could lead to inner-european conflicts escalating into wars. Sure, right now Russia is the enemy, but who knows what'll happen in ten years. And the military machinery is not just going to be scaled down immediately.

If he's being downvoted for his "selling weapons to Israel" comment, I just want to highlight that even a majority of Germans is against it, with 80% not wanting to send weapons [1]. Of course there are different polls, and others find that "only" 30% say "stop them", plus another 43% saying "limit them [2]. Either way, only a small minority is pro "send all the weapons".
