Ukraine

That cannot be allowed. NATO should reply that if a single NK soldier steps foot on the frontline in Ukraine, it will respond in kind with Western troops, unlimited weapons, and no more restrictions.

I think this could potentially be a bigger deal than the idle nuclear threats that Putin rattles off every other day.

Edit: It will also be interesting to see hoe South Korea responds to this. No way they do nothing, right?
This is a bit far for me. Definitely take the gloves off of Ukraine regarding where they can strike with US/NATO-provided weapons. But, NATO ground troops??

Asking this question not to provoke, but to better understand where you are coming from in your post: if you had a son/daughter/grandchild who would be one of those infantry mobilized to go fight on the front lines in Ukraine, would you still hold the same opinion?
