Why must some people not like revolution?

What I'm Talmud about is some people trying to stop the corrupt, unlawful, unemployed countries with unfair polices such as Libya and other Africa- mideastern protest goig on right now. I agree for the fact that America was once a coutry that was trying to overthrow British in the u.s.a and we got some help from the French and the rebel army of America fought for it's indipendince from Britain and right now they are and they need are help. The leaders a re abusing their powers abusing people rights and worst of all not doing anything about it but kill them and they need a fairer land for there citizens not that were helping every country but we try to help them still. Thank you for reading and tell me you option as a human.
