Recent terrorist attacks in Ahmedabad, Bangalore, Delhi seemed low-tech affairs: crude but powerful bombs placed in crowded areas. Easy to do and impossible to prevent. What happened in Mumbai seems altogether different. These terrorists were well-armed and well-equipped, and the whole sequence of attacks seems to have been planned well in advance. It is certainly a failure of our intelligence, as well of the security systems in place at the hotels concerned (it is much harder to enforce security at a crowded railway station like CST). It seems clear that this is a larger and better-connected group than whoever set off the previous bombs.
In other news, the England cricket team has called off their tour. I wonder why they didn't leave England when the London underground was bombed in 2005, or when the IRA was wreaking havoc in the 1980s. Life must go on and the terrorists must not win -- unless they're someone else's terrorists.
