There's a class of people in the West who have forgotten that wars happen and that defense is necessary. American especially benefit from two oceans separating them from the rest of the world and having never seen a war except on CNN.

Some of them, esp in central/eastern Europe, were rudely woken up in 2022 when Russian tanks rolle into a neighboring country. Others still have their heads buried in the sand and will not wake up even when Chinese robots march in Taipei in a few years.
