The vet’s wrong.
You CAN’T bomb an ideology.
You can only kill the people who hold to that ideology - and that’s a vastly different thing.
And, as Sherman said, when you have killed a certain critical mass of them they grow fond of peace ...
You must destroy pursuit of an ideology, which leads some to believe they are the chosen people, by utterly destroying the faith in it’s tenets. Only at the point of obliteration will these people consider a different path.
