The fear of make believe history out of Data's mouth?

The episode was first filmed 17 years ago, and now, in the next few days,
it will finally be shown for the first time in Ireland. The episode is
"The High Ground" from "Star Trek: The Next Generation"
that first aired in the United States in 1990. While most of the TNG
episodes eventually made their way to other countries, "The High
Ground" never aired in Ireland.

Was it censorship? Or was it an effort to keep the peace?

The beef the government and critics have had against the episode is a
simple line Data (Brent Spiner) speaks in the episode that says Ireland
won't unite until 2024, and only then because the terrorists in that region
would be successful. Ireland spent years with constant infighting, and in
1990, didn't seem to have any end in sight.

..

Ireland wasn't the only country that never had a chance to witness
"The High Ground" -- at least through government sources like BBC
and RTE. None of the United Kingdom has seen the episode where Dr. Beverly
Crusher (Gates McFadden) is taken hostage by a terrorist organization that
feels violence is the only way they're going to be heard. The episode would
be aired on Sky One in an edited form, but would actually be aired unedited
by the provider in May 2006.

"People will see the funny side of an occasion on which the powers
that be decided to censor an episode of a popular science-fiction series
because of what was happening politically at the time," Kelly said.
