What is the difference between "Initiative" and "plan"?

I can't see much connection between them - what context were you thinking of?

"Strategic Defense Initiative". In fact,from the context of the article,I can roughly know that's a kind of plan.I just want to know the usage of "Initiative".Does it mean more than just "plan"? Thx a lot!

initiate: to cause or facilitate the beginning of : set going <initiate a program of reform>

It is a kind of plan, but more than just the generic idea of plan. It has to do with taking the first step toward some goal, i.e., initiating something. It's not unusual to see this word used in connection with U.S. legislation.

Ah yes it does get used in that way. I'd see it as more synonymous to 'project' than plan.

Thx!That helps a lot.

It's a good idea. But I don't find any relationship between them.

initiative: shows drive/impulse in action
plan: shows thought
