> I lack fighting spirit, don't want to spend money for weapons and I'm not afraid of Russia (live in Germany).
Aren't those statements contradicting as at least two separate sets of ideas?
If you lack fighting spirit, you don't want to fight. So you should want more money spent on weapons, so that you don't have to fight. Aristotle said "if you want peace, prepare for war".
If you don't want to fight, you should be afraid of everyone who does: e.g. russia.
putin clearly said he wants to restore the old ussr borders. This means eventually taking eastern Germany. And then you just have to naively assume if he succeeds at that, he will stop at that. I mean, let's be honest, he can't possibly live that long to see his plan fully completed, but let's say he has successors continuing his work.
I know that there is this comfortable seemingly impenetrable boundary of NATO alliance: but recently Trump said he would invite putin to attack on NATO members that don't put enough GDP % into military spending (e.g. Germany), and new Slovakian government is significantly more prorussian (meeting with russia and Hungary).
In January 2022 experts almost unanimously said it would be ridiculous for russia to attack Ukraine.
Don't be afraid of russia, but also act to actually support your peace of mind.
