During a concert in England earlier this month (Jul14), the Pearl Jam frontman launched into a rambling rant about war, telling the crowd, "There are people out there who are looking for a reason to kill!... They're looking for a reason to go across borders and take over land that doesn't belong to them. They should get the f**k out and mind their own f**king business."
Vedder was not specific about who he was targeting, but he has been criticised by Israeli groups, who feel sure his frustrations were aimed at them amid their ongoing conflict with Palestine.
Now Novoselic has come out in defence of Vedder in a post on his blog, which reads, "Thank you Eddie Vedder for speaking up for peace in our world."
The former Nirvana bassist adds, "Eddie has gotten some criticism over comments he made about the conflict between the Palestinians and Israelis. That situation has been messed up for so long, it is no wonder that even mentioning it is toxic.
"The people of Palestine and Israel deserve peace and prosperity. It is time to stop repeating the same old arguments, dogma and hate speech. It is the knuckleheads on both sides that should be criticised and not the singer from a rock band.
"In addition, both sides need to make hard decisions about finding a settlement to the catastrophe that is Israel/Palestine. Thanks Eddie for sharing your feelings. I stand with you my friend!!!"
At the end letter, Novoselic posted a video clip of John Lennon and Yoko Ono singing Give Peace a Chance.
Take a look back at October's inaugural event.
The film is expected to continue without Mendes' involvement.
