It should also be noted that Israel's Law of Return is a foundation stone of Zionism itself, and its mission to bring back the Jewish diaspora to Israel - not just any nation, but an entire religion's spiritual homeland and according to the religion's eschatology the future seat of global governance after an end times prophecy has been realised.
The religious significance of their Law of Return should not be downplayed, and is highlighted by the fact that
"Jews who have converted to another religion are not eligible to immigrate under the Law of Return, even though are still Jews according to halakha".

Given Israel's history, their specific Law of Return is uniquely positioned in terms of its ethnic, religious and national significance. None of the other countries' Laws of Return you mentioned have quite the same characteristics. To qualify my own view, this doesn't mean, therefore, that all Jewish people should be viewed with suspicion, or are planning a hit-and-run. I feel the need to state that considering the amount of paranoia.
