If true, (is newsweek a reliable source for Iran coverage?) this would be an immensely risky and possibly stupid move. If they will kill you for protesting what deters you from terrorism and assassination?
Newsweek isn't a reliable source for any coverage. It essentially went under in 2013 and its brand assets were acquired by a company with deep ties to "The Community", a Korean religious sect (parallels to UPI and the Unification Church). Regardless of how you feel about "The Community", the Newsweek you're seeing today has essentially no relationship to the historical Newsweek.
It's always worth checking the bylines on Newsweek articles and trying to trace back where the writers came from. For awhile, most of the Newsweek stories I saw were written by people with SEO backgrounds, not journalists. (You might reasonably be fine with this, too, but the branding is misleading).
I think my first clue was when they "outed" Satoshi Nakamoto as a completely-random retired Asian guy in SoCal. Guess that happened after the acquisition by the Korean sect. I hadn't heard about that.
This isn't true. Newsweek is reporting an unverified tweet which is from an account focused on the conflict in Ukraine. The tweet itself seems to be referring to the letter on sunday signed by 227 lawmakers urging the death penalty.
The fact that they will likely take it out on your family, friends and anyone suspected of knowing about your actions. Not to mention the shit that happens before they kill you.
