Sara Rifka,
You live in a country, surrounded by enemies. Torah is against worshipping force and might, but Torah is not against having an army. When Torah gives a brocha that you will defeat the enemy – it will be, and was, with your army. And if there is a need for the army, then you can’t say “my blood is redder than yours”. This is also our tradition.
And, while learning Torah is a great thing for everyone, we never had in recent history luxury of large part of population learning and doing nothing else. Great Volozhin yeshiva had up to 400 students.
