The homosexual molestation of adolescent boys (let's call it what it is) was a U.S., not an Irish, problem.
It (and the cover up) was confined almost exclusively to dioceses run by "modernist", "progressive" administrations. Those were the people who believed the modern, progressive psychiatrists who said these perverts (and perjurers of their vows) could be "cured".
When JPII discovered that certain archbishops had been lying to him, he dropped the hammer. Since B16 has been handling these cases directly since 2002 or 2001, he knows the score and he will continue to attack it.

It was an Irish problem too. A number of priests from my own county (Donegal) were implicated. Nationally, there were several horrific cases such as Fr Brendan Smyth (who was moved from parish to parish for decades and eventually caused a government to fall) and Fr Sean Fortune (whose exposure led to the resignation of Bishop Brendan Comiskey). Those two were merely the worst though.
