It's sad IMO, that allies have not responded to the escalation from Russia using North Korean soldiers.
I'm not saying we must send soldiers to the front, but I'm sure Ukraine could use some help with maintenance of the western equipment for instance.
Allegedly one of the reasons it took so long to get F16 to Ukraine, was the training of ground crews. I think under the current circumstances, we can easily justify helping Ukraine with such things now.
I don't think we (Europe) should wait for USA, Trump could also decide to end all US aid to Ukraine, which I personally find more likely.
He would then claim it as a victory, for saving tax payer money, despite he is undermining American interests internationally, and aiding Russia that is an obvious enemy to USA.
Trump is compromised, all his actions regarding international affairs show this.
