Who is the Real Terrorist!

I have a question that who is the real terrorist.
Every country and person thinks that muslims are terrorist .
Is this true lets have a look on it.
In the whole world mostly people are killed by terrorists are muslims than how you can say that muslims are terrorists.
If you look on Palestine, Iraq , Burma and Kashmir , every day lots of people are being killed and their life is very hard nut to crack.
In Pakistan we lost 70 '000 lives against terrorism.But people say Pakistanis are terrorists. They dont deserve to live life happily . Why we cannot live happily .
Few days ago , A person killed 50 innocent muslims and all international media and countries are saying it is shooting not a act of terrorism.
Why when a muslim does a negetive act he called terrorist and all nation also , but when same act does a non muslim , it is not called act of terrorism why!
We want to live happy and wat to see whole world living happily .
And to promote that we are peacefull and want peace .
Thanks .
