I sense potential for a floating "Variety" massage parlour.
LOL.
Thailand has no naval fighters anymore. So sell it to others who has and need.
To be honest, i agree with you. Thailand really has no 'hostile' neighbors. They are cordial and in partnership with Myanmar, they cooperate with Malaysia and Singapore. And to an extent they also cooperate with India.
Who else do they share a border with ? Cambodia and Laos? lol.
Thailand should focus on her air force, and ground capabilities. Navy wise -- they don't need subs, but frigates with anti-sub capabilities.
