Korea was a UN action to restore the status quo ante North invasion, 25/6/50. US accepted the co-ordination role, from its Occupation Force on Japan. Netherlands combat types were departing Indonesia (bar W.Irian) exactly then, 25-27/6/50, and their transfer to S.Korea would have been confusing; France was pre-occupied in Indo-China, UK in Malaya and nervously holding Spitfire 14s in HK. RAAF exactly then, 16/7/50, had started Lincoln ops. alongside RAF on Tengah: so those UN Members were already doing their bit to oppose Sino-Soviet excursions. RAAF and SAAF F-51D could readily interoperate with USAF/PACAF and were welcome: MacArthur did not need RAF, a logistical confusion. RN/RAN were very welcome to share the burden, as were soldiers from the willing.
