Easy to assemble, quick delivery, comes with instructions and it works. Much, much cheaper than a flatbed disrupting economies in the Mediterranean Sea.
The concept of 'No Fly Zones' worked in Iraq, but, the geography is very different. The Mediterranean Sea is not a good place to disrupt.
Right now the evacuation of people out of Libya is going well. I realize the refugee problem is a sincere problem, but, it is not as great a problem of logistics if there are problems in the Libyan waters. There would be a lot of ship traffic disruption including relief efforts. It is prudent to seek other methods of resolve.
There is also the issue of 'inviting' unwarranted jihadists to Libya when all the people are trying to do is liberate themselves from dictators. The problem as it presents itself today is how to remove Gadhafi from Libya for war trials. That is the problem in a nutshell. A war is the last thing the people need. And no matter how succesful the No Fly Zone over Iraq was, in the long view it is wrong to gave permission for more than should have occurred. I don't think anyone needs to revisti the truth on that issue, the facts stand on their own in regard to Iraq.
The problem is Gadhafi. It is that simple. He is a criminal by every measure. The proceedings to declare him a criminal and issue a warrant for his arrest needs to occur to justify the actions of the United Nations both in securing the Libyan people and providing relief efforts. Issuing a warrant for him will send a clear message to his sons and others that would seek to follow his example.
Libya will be settled. The people never wanted a conflict. They wanted freedom and peace for the first time in their lives. That has to be kept at the center of any actions to assist them.
