The following explanation of the term ‘Jihad’ is taken from the website of the blogger ‘Penjihad’.
“Jihad” springs from the Arabic “Jhd” which means “struggle”; “Jihad” means the act of struggle, “Mujahid” (Plural, Mujahideen) is someone who is doing “Jihad”.
At the core (the highest level), it is the duty of every Muslim to struggle against the basic negative predispositions we all have as humans…greed, envy, jealousy, rage, deceit, theft, murder etc.
At the next level, it is the duty of every Muslim to fight against the ills that beset Mankind…hunger, disease, homelessness, illiteracy, injustice, lack of water, pollution etc.,
At the least important level, Muslims are required to fight those who attack us AFTER we have exhausted all other efforts towards peaceful resolution. Even then, if peace is at hand, even at mid-battle, one has to stop and accept terms that are just and preserve the dignity of all parties.
I would imagine these are things that every person needs to subscribe to, not just Muslims.
