This type of ban has the unintended consequence of strengthening/accelerating the domestic market of the party you are trying to sanction. This has happened with Turkey (F35/TF-x, Patriot/Hisar-Siper, the whole UAV/UCAV programmes etc.) and currently happening with China (them acquiring investing in foundry know how and capacity, Huawei investing in its own OS). Would be exciting to see what this one will bring.
