This question is based on an incorrect underlying assumption, namely that Nixon had anything to do with Pakistan's nuclear arsenal. Pakistan acquired Nuclear technology in 1999-2000. Nixon died in 1994 and resigned from the Presidency in 1974. There is no way he could have allowed them to gain nuclear weapons.
The US signed the Comprehensive Nuclear-Test-Ban Treaty in 1996 which prohibits nuclear testing. Additionally, advancements in technology allow for testing through simulations and monitoring. The US also aims to set an example for other countries to follow suit in reducing nuclear proliferation.
If by strongest you mean highest yield, I believe this would be Russia. Current treaties allow them higher yield weapons because their ICBMs are somewhat less accurate than US ICBMs.
The primary means of delivery of nuclear weapons is by missile, either from a land based missile silo, or from a submarine. However, they can also be dropped from planes (like conventional bombs) or smuggled into a target zone as luggage, if security measures are sufficiently lax. Even nuclear artillery shells exist.
yes it is completely allowed in Pakistan
South Africa, Canada and Libya. South Africa developed six nuclear weapons under the apartheid government, but they voluntarily disarmed right before the fall of apartheid because 1) there would be no need for a country that wasn't white supremacist anymore to have nuclear weapons in Africa, and 2) they worried that the ANC might proliferate nuclear technology if they got their hands on it as they had a history of relations with leaders like Gaddaffi. Canada, long a major center of nuclear technology R&D, inventing the CANDU reactor and other pieces of nuclear technology, could have very easily developed nuclear weapons but chose an anti-nuclear stance and stated it wouldn't develop the bomb or allow other NATO states to station nuclear weapons on it's territory. Libya was very close to completing a nuclear bomb but Gaddaffi voluntarily gave up his nuclear program and let the US in to remove his weapons after Bush made an example of Iraq. He feared they'd invade and institute regime change in Libya to if he gave them the excuse of WMD program.
Einstein was always opposed to all weapons, not just nuclear. He really saw no difference between a rifle and a nuclear bomb, both killed.He had signed the warning letter (written by Leo Szilard in Einstein's name because Einstein was famous and Szilard wasn't) because he was more afraid of nuclear weapons in the hands of the Nazis than in the hands of the U.S.Even though he signed the letter, he really wished that physics did not allow the construction of nuclear bombs. But the first warning of the letter was that the U.S. had to determine that first. As it was soon shown that physics did allow it, the U.S. began work on making them just in case the Nazis were doing so also, so that we had a "defense" by attacking back.
Asif Ali Zardari is the President of Pakistan today, and Pakistan's constitution does not allow for a vice President.

All of this hinges around the Nuclear Non-Proliferation Treaty (NPT). This was a treaty that was made by the first five countries to have developed nuclear weapons or nuclear power technologies: US, USSR, UK, France, and China. These countries passed the NPT to prevent nuclear weapons to arise in any other country. According to the NPT, if a third-party country joined the treaty as a signatory, that country would be bound to not produce any nuclear weapons and would be subject to inspections, as determined by the nuclear powers (US, USSR, UK, France, and China), to make sure that no weapons would be produced if there was a serious doubt that production was occurring. However, there was a huge upside, namely that any signatory could have the direct assistance of one of the nuclear powers in setting up their own nuclear power facilities, meaning that these countries would not have to spend decades reinventing nuclear technology. Iran signed the treaty, while Israel, Pakistan, and India did not.Since Iran signed the treaty, they are held to the requirement that they allow inspections and the treaty also gives the US the leverage over Iran. Conversely, since Israel, Pakistan, and India did not sign, they had to invent nuclear technology from the ground up. Israel likely achieved this in the 1960s. India and Pakistan both achieved this for certain (because of nuclear tests) in the 1990s.Since the US, Russia (successor to the USSR in all treaties), UK, France, and China were the authors of the treaty, they exempted themselves from the requirement to be inspected. Besides, everyone already knew that these countries had nuclear stockpiles and would use other treaties to limit them.As for other nuclear energy countries, like Japan, those countries do have to agree to inspections of their facilities by international observers. This is quite a common and regular occurrence with very little enmity from Japan over the international inspectors. However, there has never been suspicion over Japan's nuclear program given the country's severe limitations on having a military. This is why the inspections are rather lax and not much diplomatic effort has been spent on forcing compliance.
