Good yidden are all looking for ways to improve themselves as a zchus for our soliders who are fighting מלחמת השם against our sworn enemies.
I have a few ideas. Here is one: The pasuk in Ki Teitzei says very clearly that is we are careful about matters of modesty then Hashem will protect us from our enemies at war. If we are not then the Shchina departs from us and we are left exposed to their attacks, Rachmana litzlan.
כי השם אלהיך מתהלך בקרב מחניך להצילך ולתת אויביך לפניך והיה מחניך קדוש ולא יראה בך ערות דבר ושב מאחריך
If there is a lack of modesty, then ושב מאחריך - the Divine Presence departs. If Hashem is with us - we win. Indeed the pasuk refers to the army camp and we are not in the army but we are all connected to and part of Hashem's army and feel very strongly about our wish that Tzahal suffer no casualties.
So my suggestion is that ..... all of the bungalows that have mixed swimming put a stop to it for the next few weeks as a zchus for our army. How about that??? And the coed camps separate the boys and girls as well. It's actually not my idea. It is ... Hashem's. That is why it is in His Book.
