Protest plans: The Irish Anti War Movement (IAWM) has called on all political parties to boycott any meeting with President George Bush next week
A "major mobilisation" is being organised by the organisation to Belfast on Monday.
"We will be running buses from Dublin and hopefully from around the rest of the country," said the IAWM's chairman, Mr Richard Boyd Barrett.
"We intend to give George Bush a welcome he won't forget and let him know how angry people are at the murder his government is committing in Iraq.
"We believe the Taoiseach should take the opportunity to tell George Bush that the majority of Irish people want no hand, act or part in this immoral war by the use of Shannon by the US military," Mr Boyd Barrett told The Irish Times yesterday.
The Socialist Party TD, Mr Joe Higgins, called President Bush's visit "utter hypocrisy".
"If the Taoiseach reflected the views of the majority of people in this State he would boycott Bush's visit," he said.
"I'm going up to Belfast on Monday to protest.
"The visit is at very short notice and that is deliberate to leave very little time to organise protests.
"There is a lot of anger about this because of its cynicism. The US is shredding women and kids to bits in Iraq and then coming here to make peace," Mr Higgins said.
It was clear the "real agenda was for Bush to try and pose as a peacemaker and use the North as an alibi" and to "divide up future use of Iraqi resources".
"They'll take oil to pay for damage done to the country, then for profits.
The Iraqi people will pay one way or another. It's all a set-up," said Mr Higgins.
The Green Party chairman and foreign affairs spokesman, Mr John Gormley, said the party was considering organising a protest on Monday.
"This is obviously not welcome news. We see Bush as a warmonger, and no welcome should be given to a warmonger," Mr Gormley said.
"At a time when we are seeing innocent Iraqis killed it is inappropriate to make such a person welcome." .
