QUESTION: “Should Jews Go on Vacation while Israel is at War?”
===========================================
If we want to discuss this question correctly,
then we must recognize 3 different categories:
[1] Category 1 is those who live in Eretz Yisrael, and suffer because of the war.
[2] Category 2 is those who live in the exile [galut], but suffer from serious troubles.
[3] Category 3 is those who live in the exile [galut], in comfort and prosperity.
Which of the 3 categories does the original question refer to?
The answer for Category 1 is not the same as the answer for Category 2.
The answer for Category 2 is not the same as the answer for Category 3.
