Earlier quoted context omitted.
If Russia decided to full-on invade Ireland, a country of 4.5 million (as completely absurd as this idea is, being Ireland where it is) having its own military would not help Ireland- it should better capitulate quickly to limit damage.
There's a similar population ratio between the PRC and Taiwan I believe, so I guess Taiwan should just give up on having a military entirely then? Not possible for them to stop China, so why bother? Just lie back and think of Ireland.
Btw, do you also happen to think that Ireland should arm itself against a possible invasion from the US?
