If some level of violence is necessary to ensure peace, the people entrusted with the power to inflict said violence should be compassionate and wise humans not, "rough men".
And at the same time we should be putting our resources to work at lowering that necessary level of violence.
Beware "rough men" who project themselves be "compassionate and wise", lest you end up with a John McCain-type who says all the right things at home, but then wants to kill people overseas for profit.

Oh I agree, but during the Trump years he (and even W. Bush) were lionized as these "class act" figures just because they didn't tweet recklessly, as if there's any class to their foreign policy.
