An end to third world air forces?

Okay, who has been screwing with the forum? Geez u turn ur back for two seconds and someone has to mess about! All seriousness though I like it.

Okay, is it just me or are aircraft becoming too expensive for the worlds smaller air forces to purchase? For example, how can countries like Angola, Cuba, Cambodia, Bulgaria or El Salvador be expected to purchase EF2000’s or Rafales to sustain their air forces in the future?
Does anyone else think we will see the end of national air forces from nations such as these unless a new cheap fighter is put on the market by either US or Russia?
How can nations such as these be expected to defend themselves unless such an aircraft is introduced?
