Why do Muslims (I'M NOT TALKING ABOUT ALL MUSLIMS) have to be so land greedy?

I'M NOT TALKING ABOUT ALL MUSLIMS- I AM TALKING ABOUT EXTREMISTS- PLEASE REALIZE THIS BEFORE YOU JUDGE THE QUESTION. They want to convert everyone in the world to Islam, but aren't these Crusades hundreds of years old already? I mean all religions are starting to be at peace (not total peace, but not macring eachother), then muslims just come in and start causing trouble. I'm not just talking about Israel, but also Pakistan. They ruined an ingenious, saint-like man's plan to finally have peace in India (Gandhi). After being saved from British oppression, they just want more and more Indian land! Can't they just get along with Hindus and Jews? It's not like Jews and Hindus travelled all over the Middle East and Asia converting people to their religionand maccred many people (I'm talking compared to the slaughtering muslim extremists have done). I used to think muslims only hated jews, but extremists seem to utterly despise and want to kill any non-muslim- shouldn't they adapt to the 21st century already and stop with this medieval bs?
