Question I have been asked: Is it safe to travel to Bangkok now and immediately after the February 26, 2010 Thaksin asset ruling?
Yes.
As of 24 February, 27 Countries have issued some kind of travel advisory (http://bangkokpost.com/business/tourism/33418/tat-prepared-for-crisis ). Safety is dependent upon the individual- the protests are not a tourist attraction and should be avoided.
The protests are usually confined to a small portion of Bangkok- around the government buildings and are contained by the police and military. Generally most of the protests and gathering have been very peaceful, even the large gathers have not always lead to violence and problems. Most of the time the protests are planned and communicated to the Thai Government, there are not roving bands of protesters wrecking havoc and violence all around Bangkok.
But, as with all media, peaceful protests don’t make for good CNN style newsdrama and only the protests with issues and violence receive coverage.
Any protest is about the Thai people and their politics; foreigners are not involved and are not targets. I was in Bangkok for the April 2009 protests and arrived back in Bangkok 3 days after the airport was re-opened. I didn’t see any violence and only small signs of any changes- but I avoided the areas where the protests were being held.
Don’t be afraid to travel to Bangkok and Thailand, but be smart. In major cities across America, you know which neighborhoods to avoid late at night- use that same judgment if you are visiting to avoid protest sights.

There is nothing we can do if something happens. But as you said this is a problem of Thailand and its people. This is nothing whatsoever to do with foreigners . Provided that people avoid the areas where the protest is likely to take place, the inconvenience is unlikely to affect innocent Thais and ordinary foreigners. Hopefully nobody is going to blockade the airport again. I seriously hope not.
