And what exactly do you find funny in that?
Nope BAF will not train/cooperate with IAF. After all IAF is the top potential threat for BAF. And for some time our pilots are already flying these in China and Russia. In future not IAF, but BAF shall be training RMAF and Indonesian AF. pilots.
You are a jamaat sympathizer so you're views are on the expected lines.
However, it is highly doubtful that should BAF procure Su-30, the trainings would be conducted by RMAF or Indonesian AF.
The Govt and Military in BD would in all likelyhood choose the Country that is training the RMAF and Indonesian AF - ie India.
As far as Chinese and Russians are concerned, they cannot be used for the same reasons that Malaysia and Indonesia went to IAF for training. The Chinese flankers are not the same that you will be procuring. They are very different with different physical characteristics and outdated equipment.
And the Russians do not have in their own service, the variant of Su-30 that IAF, RMAF or Indonesian AF use. While this is okay for the BAF pilots to gain some hands on idea of how the flankers work - which is what they are doing now, it is not okay to do any kind of extensive training including combat training over different and outdated versions of the aircraft.
Ergo, the logical choice for both BAF and GoBD will be India for multiple reasons - a very large airspace in India to practice, a very very high experience level and the fact that the flankers in this side of the globe will most likely be sent to India for maintenance and overhaul because its much cheaper compared to sending them to Russia.
