NATO planners would need at least a couple of weeks just to prepare the details.
NATO planners, for example, have prepared plans for a "deterrent force."
"I couldn't agree and describe a mission that had not yet been developed by NATO military planners or recommended to us," he said.
NATO planners must also be careful not to thin their forces so far as to invite harassment and attack.
NATO planners estimated these numbers could provide "a certain degree of security by military forces against attacks and terrorism."

NATO military planners say they fear this second phase would be a big step toward a "denuclearized Europe."
It seems that NATO planners are considering 25,000-35,000 soldiers, and under one plan, even 60,000.
A total force of 28,000 is being considered by NATO planners in Brussels.
NATO planners are to arrive here on Wednesday to discuss a larger peacekeeping force.
