As George Monbiot says, the answer to thwarting a fascist movement & its inevitable wars, is using tax dollars to benefit the citizens & voters of a nation, all of them, not just the 1% at the top.
Also, ensuring that the top pays their taxes.
It was the Post WW2 answer that worked for 75 years. It created trade not brinksmanship. It created diplomacy and mutual aid treaties like NATO.
That's the solution.
Tax the rich.
Good government geared towards the needs of the nation.
