The problem with articles like this is that the news overtakes them quickly.
The U.S. just announced that it's sending M-1 tanks to Ukraine. This was a sticking point for Germany.
Most of these kinds of decisions happen in smoky rooms (maybe not literally, anymore - unless it's vape, but you get the point).
By this I mean that I am confident in saying that the Germans had already agreed to allow Leopards to be sent if the U.S. would sent a few M1 Abrams.
Now that the U.S. has agreed to do so, we will soon see a stream of Leopards rolling into Ukraine.
Whether this escalation of the war finishes off Putin or finishes us all off is going to be the trillion dollar question.
