I think they should thank them because,we might not have new stuff. Also they work hard to get new stuff for them to. So are responsibility is to thank them for what they have done for us thank you veterans.
We should always celebrate veteran's day because many veterans risk there live to help this country. Even if you don't like to celebrate veteran's day at least thank god that your country has won another war. I always celebrate veteran's day because my uncle is a veteran.
