Israel didn't, and still hasn't, claimed to possess nuclear weapons. While it now is widely believed they do, that is far less of a deterrent. It's also worth noting that the US, one of Israel's closest allies and possessing arguably the best intelligence apparatus in the world, was not aware that Israel had the bomb until 1975, it's extremely doubtful the surrounding arab states knew earlier.
None of the conflicts between India and Pakistan since either of the powers got Nuclear weapons (1974 and 1998, respectively) could be reasonably characterized as invasions.
The Falkland islands are a British overseas territory. They are self governing, but the UK is responsible for their defense and foreing affairs. Classic protectorate. Obviously invading the Falklands is very different from invading the UK.
I guess you could look at their non-admission as evidence to the contrary, but it's not like they're selling enriched uranium as a souvenir to tourists at Ben Gurion international.
Further, while it was widely suspected Israel had a nuclear weapons program, that's a very different thing than having a bomb. Iran is believed to have had a nuclear weapons program. So have many countries.
That's very much not what matters. If you wanted to travel to the UK and your plane took you to the Falkland Islands, you'd be very pissed off and say "you didn't take me to the UK!" If someone says "where is the UK?" the correct answer is not "the south Atlantic." There is the United Kingdom the nation and United Kingdom the place. An invasion means troops in the place.
