There are only 5 military missions. Attack / Defend/ Withdraw / Delay / and Reinforce/ Any thing else is political and should be accomplished by politicians.
True enough. But what President Bush committed the country to (without any debate) was an open-ended mission that was absurdly defined as a “War on Terror”. Proving that nobody was doing their homework.
I suggest you go educate yourself because deterrence is the principal reason for having a force in being - to persuade others to resort to diplomacy rather than military action.
These are not missions. They are tactics.
