...is based on multiple conversations with least a dozen people I know in Portland, from their first-hand observations. Those observations include those of two people who have been involved in protesting (peacefully) at the ICE facility.

In addition, I have very recently visited Portland myself. I've been going back and forth between Japan and the US on personal business quite a bit for the last several months, although mostly between Tokyo and Phoenix/Scottsdale. I'd be curious to know where these "Antifa" occupied blocks are, as I saw nothing of the sort (although that was not, obviously, the purpose of my trip).

While Portland has the usual big city problems with property crime and high levels of homelessness (the latter being pretty extensive in Portland, to be sure), there was nothing that remotely justified military occupation...or anything beyond substantial reform of the (useless) city government and police force. That's a matter for the state, not the feds...and I stand by that unbendingly.
