Both sides are culpable. The "proddies" and the Catholics have been going at this for years.
Saying that it's the fault of one side only is complete and utter denial.

Divesting Ireland from the UK may be a band-aid on a serious wound. The real issue is
religious ideological differences which must be addressed and mollified. The model is currently at work in the Mid-east for these differences.

The problem with a Marxist solution is that it offers an extrinsic or outside solution to
an internal problem. It doesn't deal with the religious ideological differences. Marxism as applied is a "religious" approach to the problem in itself whether a god is mentioned or not.
Marx was principally an economist and not necessarily the final word on how a government should be run. Stalin certainly abused Marx and his theories for totalitarian purposes.

I believe as in the Mid-East, outside arbitration by a credible world body accepted by the world community is the only answer.

Apparently George Mitchell has had some influence in the "peace process". My hope is that Obama will work toward goals of harmony in these conflict-ridden parts of the world. Before that, though, Iraq and Afghanistan problems need to be resolved.
