More of an update on the feelings here:
Things have definitely calmed down and got back to normal in Bangkok now.
On Chinese New Year though there was some more bombs and violence in the 4 Southern Most provinces. The Muslim criminals there are violent on most days, but they made a concerted effort to hurt many people on Chinese New Year.
Hmmm, I am definitely making sure my family avoid crowded places during Thai New Year. I think it would be a good idea for people to avoid places like Khao San Rd and the main bus terminals during Songkran (Thai New Year). I think it seems likely that some of the Muslim lunatics and their supporters will want to use this time to hurt people and I think more and more it seems likely that they will try to hurt Westerners and get media attention.
None of this is definite, but it is just the feeling I am getting. Hopefully it wont happen.
The airport and such places - although I am sure the criminals want to do something there, I suspect it is all too hard. Crowded and busy places where they can leave a bomb, get back into the crowd and have a reasonable chance the bomb won't be found before going off are the places they seem to like.
Bangkok seems a likely target as the Thai government is Bangkok and so it is a symbol of the people they don't like (the people that feed them and give them schools and hospitals and things). Also there is enough stupid, uneducated Muslim males in Bangkok that they will find some support there. It is also possible that they could try somewhere like Chiang Mai or Ubon, as there are big crowds there also and the Military won't be expecting that.
Pretty sad stuff. This is a small group of violent idiots. But they can cause a lot of trouble and inconvenience and sadness. Most Muslims in Thailand are very good and nice people, but I hope they can see that some others of the same religion make Islam seem very evil and cause much suffering.
Anyway, take or leave my warning. Hopefully these things don't happen. But if you are traveling with children, maybe you will want to be safe during 12-15 April and avoid likely targeted areas.
