Not wasting resources is better than spending resources invading, Thailand is puppet anyway. Japan tried to convince china to surrender as well in early 1930. Thailand is no different than manchuko. Thailand gunboat was operated to help Japan , as transport ship.

I think allies do not have resources to spare for Thailand,
US go for Okinawa directly instead of south east asia after they regain Philippines. After few too many ship lost / damaged to kamikaze, they need atom bomb which they reluctant to use in the beginning.

Uk can't even spare resources during malaya bintang 3 rebellion and need to hasten up our independent. They relinquish many territories due to risk of uprising and strong local nationalist movements.

Country that tried to resist like France in Vietnam, Dutch in Indonesia were defeated by local. Japanese occupation help people understand, no imperial is good, they need to fight.
