Israel is widely believed to possess nuclear weapons and to be the sixth country in the world to develop them, however, it maintains a policy known as "nuclear ambiguity". Israel has never officially admitted to having nuclear weapons, instead repeating over the years that it would not be the first country to "introduce" nuclear weapons to the Middle East, leaving ambiguity as to whether it means it will not create, will not disclose, will not make first use of the weapons or possibly some other interpretation of the phrase. Most estimates are that Israel possesses fewer than 200 warheads and has the ability to deliver them by intercontinental ballistic missile, aircraft, and submarine.
