An occupation might have been necessary in the long run, a fragmented Ireland with no central authority was not in the UK's interest.
In OTL the chances of an invasion were; zero, putative raids possible if there was a big enough atrocity (Mrs T getting killed in Brighton might have been it). But if the IRA had the active connivance of the Irish Gov and it was carrying out a bloody campaign in UK with many civilain casulaties, and also getting a lot of material help from the USSR, then ist possible. If you note in the senario I wrote above you had events whichg were bloodier and hardened nationalist opinion; Op Motorman is heavily contested as a result; Irish Gov activly helps the PIRA (at least unofficially), more effective campign, all lead to a senario where an invasion becomes plausible.
