The Taoiseach again appealed to paramilitaries to decommission their weapons.
Mr Ahern said that the Belfast Agreement should be implemented in total.
"We should try to move on from armed conflict by all participants and try to decommission, demilitarise and implement the agreement in total."
He was replying to Mr Caoimhghín Ó Caoláin (SF, Cavan-Monaghan) who asked how many of the tons of weapons, imported by "British government agents, acting at the behest of the British government through its various arms, to arm the loyalist paramilitaries", had been decommissioned.
Those arms, he added, had been and continued to be used against innocent members of the nationalist community.
"These actions continue almost daily and are broadly overlooked by the majority of those in the media who are so taken up with the frenzy to blame all impasses and difficulties in the process on republicans."
He asked "how many arms had been decommissioned by the Official IRA, whose colleagues or former colleagues are senior voices in the House today".
He also asked "how many tons of weapons were decommissioned by those in the IRA who supported Fianna Fáil when it first came into the House, or ascended to Government in 1932, an ascension secured with the help of the IRA at the time".
The matter, he added, had to be seen in its total historical context.
Mr Ahern said he would like to be able to cover all the answers since 1926.
"My predecessors could not extract themselves from the armed movement so they decided to set up a political party. They decided that after giving it three years of effort they should try another way.
"Perhaps Deputy Ó Caoláin, after 10 years of effort, should take that into account and we could all move on," he said.
