From the London Mail [caution tabloid]:
The international arms control regime is in a state of decay. Existing nuclear treaties are either outdated, expiring, or unratified.
Coupled with intensifying tensions in global geopolitics, countries like Japan and Saudi Arabia are seriously exploring the acquisition of nuclear weapons. The United States has long been a security guarantor to these countries but doubts about whether Washington is a reliable partner are growing. There are currently nine nuclear weapons states: The United States, Russia, China, the United Kingdom, France—collectively known as the five possessor states, or P5—India, Pakistan, North Korea and Israel.
