"Asquith, Bonar Law Churchill, Redmond, Carson, and others involved at the time, and from The Proclamation and cabinet notes" - What the **** does what their opinions are (i.e. what they said) have to do with anything - as long as they don't act on them. Only trouble is that out of that lot - the only one that WAS acted on was the Proclamation:

It destroyed the centre of Dublin
Caused the deaths of 485 people
Caused the eclipse of "constitutional" nationalism - which had been successful in improving the lot of the people of Ireland for decades - and set the precedent that violence was acceptable for future generations.
It heightened sectarian tensions and guaranteed the partition of Ireland.

Seven men for THEIR OWN and vastly differing reasons plotted in secret within their own organisation to instigated the events of the 24th - 29th April 1916.

In 1919, nine men acting entirely on their own and working on the principle that violence was acceptable lit the fuse that resulted in the Irish War of Independence - They deliberately set out to kill that day in order to provoke a military response, their only regret was that the explosives were only guarded by two policemen in stead of the six they'd hoped for.

In 1922, one man, Eamon de Valera, who had supposedly fought for the establishment of a Democratic Republic for Ireland proved his commitment to democracy by conveniently ignoring any vote that went against him by urging others to take up the gun to put things to rights according to the way that he saw things and started the Irish Civil War.

Eamon de Valera made controversial speeches at Carrick on Suir, Lismore, Dungarvan and Waterford, saying at one point,

"If the Treaty were accepted, the fight for freedom would still go on, and the Irish people, instead of fighting foreign soldiers, will have to fight the Irish soldiers of an Irish government set up by Irishmen."

At Thurles, several days later, he repeated this imagery and added that the IRA

"would have to wade through the blood of the soldiers of the Irish Government, and perhaps through that of some members of the Irish Government to get their freedom."

To attempt to suggest that they were taking their lead from the Ulster volunteers is ridiculous for the following reasons:

The Ulster Volunteers and their supporters had only ONE red line and that was being forced into a united Ireland against their will, their threat was made against the British Government NOT against the Irish Home Rule Movement. That threat was never acted on.

In 1914 when war was declared they almost to a man volunteered and went to serve in the British Army and fought against the Germans

When the Government of Ireland Act 1920 was enacted and Northern Ireland got its own Home Rule Parliament their one and only red line issue that would have triggered action on their part all but disappeared.

With the signing and subsequent ratification of the Anglo-Irish Treaty in December 1921 the conditions that had created that red line were removed entirely on the 7th December when Northern Ireland ceded from the Irish Free State and returned to become part of the United Kingdom.
