Very powerful tactic, one that is hard for a government to deal with effectively, especially in the fishbowl era of communications. The counter-tactic usually works out to the government turning the other cheek and trying to paper over the insurgents with tons of money, which can backfire -- generally when the insurgency is supported by a foreign government(s) with deep pockets.
I've just told the story of Israel's life.
Will the Europeans rethink their position on the "Palestinian" issue now that they're walking a mile in Israel's moccasins? Oh, they'll rethink, but they'll need to take a lot more punishment before they change their behavior.
More punishment is on the way. However, I note that the BBC has dropped "refugee" from this headline today:
Migrant arrivals in Greece 'surge' to 7,000 daily - IOM.
The Europeans are also set to learn the hard way how Israel's hardliners got so much political power.
