I'll be upfront - I didn't know whether to ignore the above, or answer it....
Naturally, this would entail the Germans going into Ireland and 'removing them' by force: using an Invasion force more akin to Barbarossa than the sort of pseudo-heavy artillery featured in countless BBC news reports since 1969.
We know IN 100% DETAIL what forces the Germans were intending to use; there's a copy of the full
Fall Grun plan in the museum in the Cathal Brugha Barracks in Dublin.
I would be easy for the Jews to hide in Ireland, so the SS would likely to resort to torture tactics to extract information on where the Jews were hiding from non-Jews.
It's actually remarkably difficult for strangers to hide in even the most remote of rural environments; in the countryside, particularly the Irish countryside where everyone knows everyone else...and more importantly everyone
else's business!...strangers stick out like sore thumbs. Why do you think the Germans
had so much trouble inserting spies into Ireland???
A sixfoot-nine-inch tall 60 year old weightlifter? An
INDIAN Nationalist in a country with a negligible Asian/Far eastern population...even in its large cities????
[of course, it has been suggested that the entire male population of the UK aged 15-55 was to be shipped over to mainland Europe for slave labor]
More than suggested; this is another
known plank of the German post-invasion plans.
Regarding the future of Ireland in the eyes of the Nazis, it's unlikely that Hitler would allow anarchy and breakdown of Law and Order anywhere within his reach: he would have approached this problem with a sledgehammer........tanks, flamethrowers, ariel bombardments, heavy artillery , repeated shellfire on the scale of WW1, machinegun fire to quell rioting, etc.
How do you know??? Can you give me one example of "traditional" street rioting in the Greater Reich? The Paris Rising and the Warsaw Risings were all organised, paramilitary and relatively disciplined operations...
(If necessary
I'll give you one and you might be suprised at what happened...)
It would not have been very difficult for the Germans to locate the dissident strongholds, given the manner of brightly-painted identity of the two heartlands.
...NOW.
They weren't exactly like that in 1939-45!!! 
; if nothing else.....PAINT along with almost every other consumer good was virtually impossible to get hold of in Eire after 1941!
And of course - it should be noted that even today you only get THAT sort of "community identification" in NORTHERN Ireland or within 40-50 miles of the Border.
Nazi Stormtroopers are not going to wait around for a riot to start up: they will burn down the dissident areas with flamethrowers first.
And finally - as I noted before - with 100,000 men, armoured cars, and aircraft....
the BRITISH hadn't managed it in 1918-21
The atrocities against Irish paramilitiries by German artillery would have made the [admittedly heavy-handed] events of Bloody Sunday look like an afterthought in comparison .
Just on a point of detail - the deceased in Derry on Bloody Sunday were NOT paramilitaries.
Please don't continue to make the mistake that Ireland - North
OR South -
looked anything like, or any part of it was polarized
anything like, the way they look or are today. Today, Northern Ireland is on the far side of 30+ years of polarization of the community along religious and political lines...and the rest of Ireland looks just like the Home Counties - or Scotland when you go further afield from large urban centres.
The rural Ireland that you think had painted kerbstones and flags flying everywhere? How would you even pick your "dissidents" out of a landscape that looked like the set of
The Quiet Man???
Twenty years ago we had Johnny Cash, Bob Hope and Steve Jobs. Now we have no Cash, no Hope and no Jobs....
Lord, please keep Kevin Bacon alive...
