Just reading what you wrote.
"It was a delicate matter for the Germans and they were indeed hestitant to cross that line"
"after three wars in less than a century, they did not want to be drawn into another militairy conflict. It's for the same reason that NATO is treading lightly."
Again, I'm not criticizing the Germans and NATO countries. In fact, the opposite. There is good reason to be "hesitant" when getting involved in an endless regional conflict. The US never learns that lesson or the corrupt politicians intentionally disregard it to gain access to billions of dollars. Either way another disaster in the works. The disputed regions of Ukraine are now a moonscape.
What you are not getting is that the Germans were not pressured to change their own law. They did so, although reluctant, because they understood the need and urgency to do so. When the Balkan war was going on they refused to supply weapons because it was a regional conflict. This time around the implications of Putin not being stopped dead in his tracks were simply to great for them. They, Nato and Biden understand what you don't. You just are happy to trade human lives for (saving) money.
And, you may find this disturbing, but the Russian advance in Bakhmut has now been halted, the Wagner group is admitting to heavy losses, Ukraine forces are now advancing at Melitopol (which will allow them to cut of Russian supply lines to Crimea) and Putin is now admitting that the economic sanctions are taking their toll on his country. The U.K. has now supplied tanks to Ukraine, as have Poland and Germany. It may take a while but the right side is winning... and all you can do is complain about how much money the US is putting into it. It's pathetic!
