What were the potential market for the Mirage 4000?

assume the Saudis chose the M4k instead of the Tornado (something which probably would’ve been better to begin with).

what other air forces would’ve potentially wanted such an aircraft/capability?

i would argue that eventually it would’ve been adopted at home (and the 2000D and N wouldn’t have been developed in response, and instead of the Rafale, Dassault may have made a different aircraft to follow)
Singapore
and India (and as a response, they may not have went with the Su-30, and instead with the su-34 and 35)
