DY- Of course we should yearn for Moshiach. I never said we shouldn’t. I meant a person saying “I feel bad I can’t move to EY, I can’t wait for Moshiach to come so I can go” is not accurate because one does not need to wait for Mashiach to go to EY. In other words, yearning for Mashiach and all the Mitzvos that come with it is not the same as yearning to live in EY.
Health- At first I thought you meant the 1300s and I wrote my response that way. When I realized I misunderstood I edited it quickly and added the last paragraph. But you miss my point, even if it is more dangerous nowadays than it was 30-40 years ago, does not mean R’ Moshe would now say that is assur to go because of venishmartem. You can’t assume and make up a shitah like that that R’ Moshe never said.
