You make a useful point
Do you want to be placed in a position where you can be sent into either of two war zones in conflicts which we cannot win ?
In what are now called Wars of Choice.
WOC for the politician however not for the soldier. The serviceman has since the Second World War been involved in many conflicts or potential conflicts most of which could not have been foreseen when they joined the services. Some of these too could have been WOC.
Korea was, in a way, a WOC. Then Suez. Kuwait (1961). Indonesian Confrontation was also probably a WOC as it furthered political interests. Aden, Kenya, Rhodesia, Belize - all colonial actions and not foreseen by those already in the services when they blew up.
Only the length stability of the Cold War gave us any certainty of a mission during our careers.
No, anyone joining now is joining a mystery tour that may not include Iraq or Afghanistan!
