If you were there
and the forces of destruction
were about to destroy Jerusalem
and you had the power to do something about it,
would you sit and mourn and cry?
Or would you turn the world on its head to change history?
So what is stopping you?
Turn over the whole world now!

I think this interesting and a good advice. It is similar to " Do not stand idle when your brothers, are beiing killed Al taamod b'dam reicha! This fragment of the Rebbe could very well apply to the issue in Israel about the IDF. Should every participate in the Army? My humble answer is yes. There is no prohibition in the Aseret H'adibrot, and we wnt to war with Joshua as a leader. Finally in addition, there are many "Lone" soliders that come from the Galut and paticipate in protecting Eretrz Israel- like my brother in the Yom Kippur War. and others that I know off. Why such a argument when chas v'shalom we might to confront the issue of loosing the second most cherished notion we have as Jews?
