Do u think its fard? or is it like just choice? Ramadan?

Salam Jihad can be divided into 2 categories (1)jihad in dunya only just defending our own wealth or giving birth of a baby and (2)jihad in dunya and in akheerat just maintaining the religion with wealth and soul in the war because muslims are invaded/arracked by non muslim enemies It is fard to do it It is not just a choice
