My guess is as good as yours. Everyone and their mother has an opinion and can create a twitter account.
The question is, if Germany especially the SPD is in cahoots with Russia in some form or way, or is it the typical German defensive behavior that we do since WW2? Better do nothing than be too offensiv? Is it even fair to judge, when we don't know what happens behind the curtain? Maybe the one political party is hindering the other? From what I heard is that our weapons, equipment and so on is not ready for use, yet. Its embarrassing but our army was put on the back burner for decades and got dried out financially. Also, the modern Tanks are so sophisticated that an untrained soldier (untrained as in untrained for that specifically Tank) cannot use it, he has to learn how it works. Its more of a computer than a mechanical Tank.
But what do I know.
I am just a citizen and can only guess.
