I was not advocating for another tiger subspecific program per se, but realistically if we do want to save a unique subspecies (and mind you we already "lost" Caspian - virgata and Bali - sondaica and Javan - balica) we need all the collections prepared to hold them on board.
Yes, the European population is quite small and for part quite inbred, however if say 4-8 collections hold small groups of jacksoni under the management of North American AZA ... what is the harm in that. Mind you the genetic testing and research of the European population of Malayan - jacksoni has been conducted by our overseas compadres in the AZA SSP.
Thirdly, the export of the 2019 born sisters from Nesles to Taipeh Zoo will ensure that the SEAZA may put greater emphasis on creating that much needed regional Malayan - jacksoni and Indochinese - corbettii next to the one for Sumatran - sumatranae (mainly Indonesia + a few other countries in the region).
ATM, the SEAZA region Malayan program is promoted by Singapore Zoo, Taiping, Malaysia and a few others in Malaysia (Negara, Melaka, et al). That population needs to grow further in order to enable the less than 100 figure for the subspecies to start to recover. The Malaysian conservation authorities are in the process of creating a breeding center for release at Lanchang.
