One impact of the Belfast Agreement is that paramilitary groups have been fully decommissioned and the British troops have been removed.
"... the IRA wants a permanent peace, that the declaration and maintenance of the cessation, which is now entering its fifth year, is evidence of that, that the IRA's guns are silent and that there is no threat to the peace process from the IRA."

It took some paramilitary groups, including the IRA, years more to come to an agreement of the way to proceed with decommissioning.

"I grew up within the military family. It was completely normal to check under the family car for a bomb every morning before you went to school, like it was just normal, normal military life," said Lisa Partridge. "Nobody would want to go back to that life." (AP News)
