Good points, but curiously if it was the F-18, F-15, or F-35 that we're going to buy, a certain section of fanboys here will undoubtedly keep silent and will NEVER even mention about things such as "cost on introducing new infrastructure, training cost, cost to operate and maintain" despite the fact that these will also apply and those US fighters were all also notoriously known to be costly to operate and maintain.
On the contrary, terms such as "network centric, datalink, engine commonality, etc etc" will be frantically thrown around to obscure the fact that those US planes are also completely new types of planes that we haven't operated before and the aforementioned downsides related to cost to infrastructures, pilot training, and cost to operate and maintain will also apply to those planes.
