A lesson to be learnt from Any war is,
No country is going to help you
A nation is always on its own. Prepare yourself to defend.
Military and defense is the most important.
R&D on latest machines and weapon technologies is most important. Even if your country is flourishing , without a proper defensive technology, enemy nations will try to plunder your fortunes.
Do not believe in Ahimsa when it comes to your nation’s defense. Remember Ahimsa is only for plants, brids and animals which does not have any motive to attack us except defending itself.
Our Soldiers and protectors (like the Police, judges) are gods. They should be always kept happy by the government.
