Don't believe it.
If they both set off ALL of their nukes it wouldn't affect you at all unless you were visiting the immediate area. The left has everyone convinced that a few nukes would make the whole world uninhabitable and irradiated. That is nonsense.
Don't forget, some 1021 nukes were set off just outside of Las Vegas, at least 100 of which were above ground. People have lived there the entire time and they used to watch the mushroom clouds from Vegas hotels. The entire nuclear arsenals of BOTH India and Pakistan is between 75 & 150 small nukes.
The Nevada Test Site is a United States Department of Energy reservation located in Nye County, Nevada, about 65 miles (105 km) northwest of the City of Las Vegas, near 37°07′N 116°03′W / 37.117, -116.05.
During the 1950s, the mushroom clouds from these tests could be seen for almost 100 miles in either direction, including the city of Las Vegas, where the tests became tourist attractions. Americans headed for Las Vegas to witness the distant mushroom clouds that could be seen from the downtown hotels.
Another myth is that our cities would be uninhabitable for hundreds of years. I disagree.
Hiroshima, Japan today.
Nearly 3 million people live in Hiroshima Prefecture, and over 1 million in the city itself.
The entire Indian and Pakistani nuclear arsenals combined are less than what was set off just 65 miles outside of Vegas above ground.
India:
Though India has not made any official statements about the size of it nuclear arsenal, the NRDC estimates that India has a stockpile of approximately 30-35 nuclear warheads and claims that India is producing additional nuclear materials. Joseph Cirincione at the Carnegie Endowment for International Peace (3) estimates that India has produced enough weapons-grade plutonium for 50-90 nuclear weapons and a smaller but unknown quantity of weapons-grade uranium. Weapons-grade plutonium production takes place at the Bhabha Atomic Research Center, which is home to the Cirus reactor acquired from Canada, to the indigenous Dhruva reactor, and to a plutonium separation facility.
Pakistan:
The Natural Resources Defense Council (NRDC) estimates that Pakistan has built 24-48 HEU-based nuclear warheads, and Carnegie reports that they have produced 585-800 kg of HEU, enough for 30-55 weapons. Pakistan's nuclear warheads are based on an implosion design that uses a solid core of highly enriched uranium and requires an estimated 15-20 kg of material per warhead. According to Carnegie, Pakistan has also produced a small but unknown quantity of weapons grade plutonium, which is sufficient for an estimated 3-5 nuclear weapons.
