Were England seeking to break loose from Ireland, she could sue Ireland for a divorce and name the Kaiser as co-respondent.

Any court would grant it.
The part of Ireland which does not desire independence, which desires it so little that it was ready to resist Home Rule by force in 1914, is the steady, thrifty, clean, coherent, prosperous part of Ireland.

It is the other, the unstable part of Ireland, which has declared Ireland to be a Republic.

For convenience I will designate this part as Green Ireland, and the thrifty, stable part as Orange Ireland.

So when our politicians sympathize with an "Irish" Republic, they befriend merely Green Ireland; they offend Orange Ireland.
Americans are being told in these days that they owe a debt of support to Irish independence, because the "Irish" fought with us in our own struggle for Independence.
