What Trump has been doing is what every single US president has been doing since... WW2 (probably before that also, but post WW2 it became really worldwide), just without sugar wrapping that was usual with it previously.
Only difference is that target of the bully is small European countries that considered itself to be ally to the US, and hence immune, and not some random country that they all collectively declared "threat to the democracy and world order". IOW, bully admirer has discovered that he can be also bullied when bully wants so.
You wanted to be in the bullies gang in order to stand up the other bully, now you are crying about hazing rituals of the bully you have chosen. While I still think it is morally wrong, it is the bed of your own making.
