Iran has a modest ambition: a nuclear warhead in orbit by 2020.
Fixed that for you.
The USA has over 7,700 nuclear warheads
Russia has over 8,500
The United Kingdom has over 225
France has over 300
China has over 250
India has over 110
Pakistan has over 120
North Korea has over 10
Israel has over 200
Iran has 0
The US has already used 2 nuclear weapons.
The US, UK, France start most wars, most overthrows, Iran none.
The US, UK, France steal resources, Iran has them.
Iranian nuclear warheads is a red herring, BIG OIL is after Iranian OIL (and their access to the sea for Caspian OIL)
Iran is way down the list as the next country who might use a nuclear weapon.
