Thank you for the question.
I think it's fair to say that it goes back to the premise of manned fighters versus other options. Most industrialized and modern nations have come to the conclusion that for their future national sovereignty and defence needs, a manned fighter remains the primary tool.
In addition, it's about understanding the challenging threat environment out there, that sophisticated systems on the ground and on the sea and in the air will threaten manned fighters. Therefore, advanced countries have been working hard to achieve fifth-generation capabilities, which is the only reasonable way of dealing with the very sophisticated threats that are evolving as we speak.
