WH reporter said she was told it was because Singapore has a lot of English Media and can do a lot of press.
I laughed really hard at that nonsense.
It appears to me that the administration is going down a bad path. Assad is scum but he keeps the real scum in check and the LAST thing we need in the ME is another power vacuum. I'm not convinced Assad is responsible for the sarin attacks and I'm not sure I care even if he is. We should be supporting both him and the Russians - moderately. In order to maintain some level of influence with both and improve relations with Putin. Mostly we should avoid expending much blood or treasure in Syria. We need to stop naïve 'nation building' in Islamic countries.
Singapore is home to a few notorious fellows who help North Korea as conduits for trade in illicit goods and relations between Singapore and the Norks have been getting quite warm and cozy.
