I know all of these songs backwards and forwards. It's a pleasure to find them all together here for younger listeners to contemplate. Jefferson Airplane's Volunteers is another strong entry. from slightly later.

The greatest anti-war album from the 60's for me is Pearls Before Swine's Balaklava. It's sad rather than angry, and in retrospect, that's probably the most powerful response.

Here's the AllMusic review, which will give you a bit of background (though incomplete).
