I never understood 'laws of war'.

there is no law in war.

Please country a only fight with this type of attacks so that the people you kill are only people forced to fight against you to protect themselves but not the civilians.

War is war. You kill and destroy a country thats it.

Its not a conflict? Russia/Putin started to attack Ukraine. Thats it, russia is bad, ukraine is not.

Oh no don't use cluster bombs they are bad / different bad than normal bombs.

Btw. if countries like the USA wouldn't create cluster bombs, Saudi Arabia couldn't use them against civilians.
