I don’t understand why she simply doesn’t leave. Yes, I know she’s being watched, but there are ways if one is determined. At this point, I think she would do more for her people if she were not there.
Being arrested again will ultimately serve no one, especially if the government feels it convenient to “disappear” her, or that she’s more trouble alive than dead.
The government would love her to leave, because they would bar her from returning. She knows this and does not leave because of that. She wouldn’t even leave when her husband was dying in London. I disagree that she could do more outside the country than in.
