CHICAGO - Protesters who've been planning for months to converge on Chicago for a pair of important world meetings this spring say they have a message:

No G-8? No problem.

The decision by the White House to move the Group of 8 economic summit to the Camp David presidential retreat while the NATO summit remains in Chicago might have split the reasons to protest. But it won't diminish the number of protesters -- tens of thousands, by some estimates -- who plan to come to Chicago for a rally and march to protest everything from war to poverty, said Andy Thayer, a leader of the Chicago Coalition Against War and Racism and the Gay Liberation Network and one of the principle planners of the Chicago protests.

"Guess what? The protests are going to happen anyway because if (protesters) are upset about G-8, they have just as much reason to be upset about NATO," said Thayer.

The Coalition Against NATO/G8 War & Poverty Agenda obtained city permits to hold a rally in Daley Plaza downtown and march to the McCormick Place convention centre about 3.2 kilometres to the south on May 19 -- only now there won't be any meetings that day. The NATO summit will be held over the following two days, and discussions are expected to include the war in Afghanistan.

The presidential retreat outside Washington, where the G-8 meetings will be held May 18-19, is far more secure than downtown Chicago and it would be difficult, if not impossible, for protesters to get close to the meetings.

The White House said the economic summit was moved "to facilitate a free-flowing discussion with our close G-8 partners," on economic, political and security issues.

Rank-and-file police officers are somewhat relieved but still worry that they're ill-prepared to face an unknown number of people, some of whom they fear could become violent, said Mike Shields, president of the Chicago Fraternal Order of Police.

White House national security spokesman Tommy Vietor said security and the possibility of protests were not factors in the decision. He said Camp David, the rustic retreat in the mountains of Maryland, was a setting that would allow for more intimate discussions.

Mayor Rahm Emanuel and police officials have insisted they can handle any trouble. Chicago has had fewer problems with the Occupy protests than many other cities, and police officials had been consulting with other police departments on how to handle large protests. Even so, many downtown businesses have been preparing for the possibility of riots and broken windows.

Chicago police spokeswoman Melissa Stratton said Monday's news won't change how the department prepares for the NATO summit. Members of the city's host committee said they still expect about 7,500 people to attend the meetings.

Joe Lombardo, a retired state worker from New York and co-co-ordinator United National Antiwar Coalition, said he believes the administration was hoping to divide the protests, especially because the Occupy movement was largely centred on economic issues. He said some people might reassess their plans for Chicago, but he believes "tens of thousands" of people from groups in the U.S. and several other countries will still protest here.

National Nurses United, the largest U.S. nurses union, is re-evaluating its plans, though union spokesman Chuck Idelson said it may be too late to make a change. The group has been planning to join protesters in Chicago to call on world leaders to adopt a so-called "Robin Hood" tax on major trading by banks and other financial institutions.

Another group, Grassroutes Caravan, which wants to call attention to environmental issues, has no plans to stay home. Twenty people have signed up so far to join the bike ride from Madison, Wis., to Chicago, said spokeswoman Thistle Pettersen.

She said the group's theme is "'No blood for oil.' We don't want wars for fossil fuels when we can use our own people power for transportation."
