Well according to the BBC, in the early 1970s, 21,000 soldiers were deployed in the North which peaked to 30,000 in the mid 70s. That represents about 2% of the population of the North. It is not entirely clear how many soldiers were present in '72 though. I would imagine more than enough to roll up and smoke the untrained, ill-equipped maniacs trying to secede if given the go ahead. Armies are not known for cowering in barracks.Do the British military in Northern Ireland have numbers to take on the mob, police etc and protect the nationalist population?
