Senior Defense Department official Amy Searight told a Washington think tank today that the Thai military has been "pretty open" that it has no interest in getting involved in running Thai politics again.
The military has taken power on numerous occasions over the decades, most recently in 2006 when it unseated then-Prime Minister Thaksin Shinawatra.
Since then, divisions have only widened in Thai politics, and last week a court unseated Thaksin's sister as premier.
Senior US diplomat Scot Marciel said it would not be appropriate for the US to seek to impose a political solution on its Southeast Asian ally. But he said Washington is stressing that the solution should be constitutional and democratic.
