Try telling the British (our steadfast allies in the War on Terror) that the IRA bombings of the 1970s and 1980s were not terrorist acts because they did not target Americans "across the Pond". Try telling the Israelis that Hizbullah is not a terrorist group because their Katyushas were not fired at American airliners.
If you do tell them that, be sure you have on your running shoes.
Neither the IRA (nor any of the other groups you previously mentioned) have the amount of blood on their hands that the Islamofascist groups (including Hezbollah) has. You forget that until 9-11, Hezbollah had more American Blood on their hands than any other group.
The idea that you can put any of those groups as an equal threat level with Islamoterrorists shows you're delusional.
