Wow, that actually happened. Saudi Arabia has basically invaded Bahrain to contain the instability there. I dunno, I think it may increase the risk of open sectarian warfare spreading throughout the Arabian Peninsula, especially if foreign troops open fire on democracy protesters.Troops from a number of Gulf states, including Saudi Arabia, have arrived in Bahrain in response to a request from the small Gulf kingdom, officials say.
It comes a day after the worst violence since seven anti-government protesters were killed in clashes with security forces last month.
Dozens of people were injured on Sunday as protesters pushed back police and barricaded roads.
Bahrain's opposition said the foreign troops amounted to an occupation.
