To the people who are still falling for the British propaganda line the troubles were just as if not more intense than the ''war'' of independence, the IRA were hitting right at the heart of the British establishment killing top politicians and members of the Royal family, it was routine for British politicians to check under their car with a mirror for car bombs everytime they went to drive their car.
There were at some years of the troubles 30,000 soldiers stationed in Northern Ireland making it the most militarised zone in the planet almost completely confined to the areas of the Catholic minority which makes the claim that soldiers were there to ''keep the peace'' irrelevant.
Also the British army took nearly twice as many casualties in northern Ireland in the 25 years up to the ceasefire than they lost in 20 years in Afghanistan.
Not to mention all the bombs that were taking out infrastructure regularly in England also in 1972 the IRA exploded 1800 bombs taking out infrastructure giving 30 minute warnings before the bomb went off, the war in Northern Ireland probably had the biggest impact on Britain by far since WW2.
Here is a typical day in 1972 northern Ireland I picked this because no one even died on this day.
