So here is a recent Q&A with Rabbi Yehuda Mandel of Bitachon Weekly (Vayikra-Zachor-Purim 5782), which also features brief yet encouraging observations from one of the recently rescued Ukrainian rabbis & Rav Simcha Bunim Cohen:
With all the Jews in Ukraine that are in danger, what does the Rav suggest we Yidden should be doing and thinking at this time?
First, it is important that every person should feel they are the one who can save the situation...
...The world was created for me. [a quote from Sanhedrin 37a – MR]
MAKE BELIEVE YOU ARE THE ONLY ONE IN THE WORLD.
Be alone with Hashem and watch your Tefilos come true.
I did just that, and the results are incredible. I davened to Hashem that no one should get hurt.
Then I davened that people should do Teshuva, because that’s very important; their spiritual deprivation is worse than their physical danger.
Most Yidden in Ukraine are not Shomer Shabbos or anything and are living out their lives without Torah and Mitzvos. We need to care about them and be M’karev them; at the very least we should cry for them.
I also davened that there should not arise Agunah Shaylos, since they were taking the men away from their families to join the war.
I bumped into Rav Simcha Bunim Cohen Shlita last Shabbos and asked him to tell me about his thoughts on the topic.
He said that the story of Mordechai on Purim teaches us how one man can save the entire world, and that this is how every individual should think.
I felt the same way during the Gulf War; I davened that no one should get hurt, and that’s exactly what happened.
Every person should do the same, and should have in mind their Ruchaniyus as well, because the Geula is around the corner, and when Moshiach comes it will not be so simple for all the irreligious Jews.
So that’s why they must be in our minds all the time. This is what I had in mind.
This past Shabbos I met the Rav of Ukraine himself, R’ Yaakov Bleich, who arrived in Lakewood. I asked him about the plight of the men, and he reported that they are all getting saved; with spectacular Nissim.
Then I asked him about their Yiras Shamayim, if they are doing Teshuva?
He replied that this is exactly what is happening.
Even their president, who is a Jewish M’shumad, called R’ Bleicher and declared: Without G-d, we aren’t making it!
So, I feel that my Tefilos are being heard, and every Yid should take credit for the Yeshua, too.
Each person should feel they are in charge.
You can “remote control” everything with your Tefilos, your Teshuva, and Bitachon.
During the Gulf War, Saddam Hussein was shooting scud missiles into Eretz Yisroel, and people were panicking.
At that time, every Gadol publicized that no one will be harmed, and that’s exactly what happened. The government was giving out gas masks [they were afraid of chemical warfare], and R’ Chaim Kanievsky said they should wear them on Purim [for a costume], and that’s what happened.
See how their positive words had an effect! Everyone should speak positively and watch how exactly that will happen.
Words are alive!
Hashem really wants each of us to be the unique individual He created us to be—a real avodah in a world that seeks to constantly distract us, keep us "connected" to people we may barely know (2000 Fakebook friends?), and to have us all think & act the same.
(That is a huge part of the reason why Hashem brought the covid-19 phenomenon into the world.)
And here, Rabbi Mandel emphasizes individuality and loneness, including the supreme importance of an individual's tefillot and deeds—and not just those of a tzaddik!—but of regular Jews.
Furthermore, Rabbi Mandel demonstrates real concern and caring for fellow Jews on all levels, noting how the coming of Mashiach—welcome by the sincerely frum (or sincerely TRYING to be frum!) will not be experienced in that vein by the irreligious Jews.
Also, it hadn't occurred to me to think of the agunah situations that often arise in wartime & displacement, but it is of course a serious concern and I really appreciate him bringing it to the forefront.
All in all, rather than taking sides and getting sucked into the false narratives surrounding us, it's best to take the advice presented in the above Q&A.
