Two Russian rockets crossed over the border into Poland today, killing 2 people. The two rockets were part of a massive barrage of missile totaling over 100 for the day.
In response to the missile attack, the Prime Minister called an emergency meeting immediately. Since Poland is a NATO member they can activate article 5, which basically obligates a response from NATO.
Since the beginning of the war there have been fears of it spilling into Poland. Now that it has, the real question is whether Poland will push us further to the brink.
