Regions Without NWFZ
The majority of non-NWS non-NWFZ states are in Europe and the North Pacific and are members of (or surrounded by) collective security alliances with nuclear weapons states dating from the Cold War and predating the NWFZ movement.
22 states are not part of a NWFZ or a collective security bloc nor nuclear weapons states, 12 in the Middle East, 6 in South Asia, and 4 in the former Soviet Union. There have been NWFZ proposals for the Middle East (e.g. Nuclear program of Iran#Nuclear Free Zone in the Mideast, 2009 UN proposal, 2011 IAEA forum), the Korean Peninsula, Central Europe, South Asia, and the Arctic.
All countries without nuclear weapons are parties to the Non-Proliferation Treaty, as are the 5 NPT-sanctioned nuclear weapon states.

Famous quotes containing the word regions:
“In common with other rural regions much of the Iowa farm lore concerns the coming of company. When the rooster crows in the doorway, or the cat licks his fur, company is on the way.”
—For the State of Iowa, U.S. public relief program (1935-1943)
