Common Foreign and Security Policy

The drone hit just after a convoy carrying former leaders and high-level diplomats, including former UK Prime Minister Boris Johnson, had passed through.

The train operators were warned of the coming drone and no one was hurt, but European leaders widely interpreted the strike so close to Poland as, in the words of Kaja Kallas, the European Union's high representative for Foreign and Security Policy, "Clearly a message to the Western world." Poland is a member of the North Atlantic Treaty Organization, or NATO.

Twelve nations founded NATO in 1949 to resist Soviet aggression.

After the Soviet Union collapsed in 1991, NATO's mission shifted toward crisis management, and then to resisting the aggression of Russia's President Vladimir Putin.

But really, it is sort of a void in Europe.

And that actually creates an opportunity for Brussels, for the European Union, for the High Representative for Foreign and Security Policy, I think, to sort of say, this is actually an area where the EU could help, could create a strategy document and say, this is a priority.

These countries we need to get to.

We need to provide support.
