BAF has been operating twin-engined fighters for a decade now. So, what is it exactly that you want to know?
If you want to know where our threat lies, the answer is both India and Myanmar; since we are not allied to any of these nations. In case of any war, it is better to be prepared than be sorry later; Afterall, we don't have any Guardian Angel.
In addition; my personal vote is for single engined fighters; but the military top-brass probably wants to counter the Burmese procurement of 20 new Mig-29s. That probably works on their mind.
