At least 22 people were killed and 59 were injured when a terrorist detonated a bomb at an Ariana Grande concert Monday night in Manchester, U.K.

On "Outnumbered" today, Meghan McCain said it's disturbing to see these types of attacks become "normalized."

"This happens more and more frequently," McCain said. "We collectively have to come together globally and realize: it is our way of life, or it is theirs."

She said too many people are politically correct and don't want to use terms like "radical Islamic extremism."

Although she's certainly had her differences of opinion with President Trump, she said he's right about the threat we face from Islamist terror.

"Globally we all have to come together and fight this cancer," McCain said.

She noted that one of the victims in the Manchester attack was an eight-year-old girl, Saffie Rose Roussos.

"Think about ... what kind of coward and monster it takes to target an eight-year-old child at a pop concert," McCain said.
