U.S. adversaries exploit power gaps. It's easier for Russia to invade Ukraine with irregular forces out of uniform, the so-called 'little green men,' than to send a conventional army that would challenge NATO.

We need to have a national security that puts steel in front of our enemies. I would send weapons to Ukraine. I would work with NATO to put forces on the eastern border of Poland and the Baltic nations, and I would reinstate, put in place back in the missile defense system that we had in Poland and in the Czech Republic.

The people who were marching at Peggy O'Hara's funeral gave the impression they were associated with the INLA, which is supposed to be on ceasefire and to have decommissioned some of their weapons. I ask if they could have honoured her in a more dignified way.
