I am not posting a lot about this because I don't think social media does fat load of any good to "help" in a case like this.
So, I'm going to say what I usually say-if you pray, then pray.
There is also a request for Jewish women to light three extra Sabbath candles tonight. I don't believe it would hurt for other people to light a candle and pray as well, that can only help.
The main thing is to live your life and raise your children to follow the G-d of Israel and understand the superiority of Western, Judeo-Christian values and cultures and the Seven Noahide laws.
You also have to remember that a lot of times, terrible things happen especially when dealing with barbarian humans who take pleasure in shedding blood and have no fear of death themselves, and not just that-bear children in order to have them kill themselves and others in the service of their deity. Mothers are supposed to protect their children and this nihilistic blood pursuit turns human history upside down. Animals protect their young, mourn their dead so we cannot and should not call these inhumane humans 'animals'. That is not the case, it is not accurate.
What else can you do?
Defend freedom on a micro level EVERY day. The micro takes care of the macro.
If you are afraid of telling a joke, or speaking freely, or talking about your beliefs in public then you cannot consider yourself a real warrior for our superior civilization. So don't be that person. Do what you can, not what you can't but realize that every action has a consequence and a reaction.
Pray that G-d guides the hands of the IDF and that they find these boys alive and well, raise your children well, never surrender, don't be afraid, do good deeds and don't buy into utopian fantasies of "peace" in some distant unicorn future for unsolvable problems. Do not think that an enemy such as this can be pacified or negotiated with. Learn the lessons of history, look the barbarity straight in the face and be willing to recognize it and fight it.
This is just a short list of achievable victories, and in my view at least, are all real things we can do while we wait for the IDF to achieve miracles.
