absolutly right - stealth thats why luxemburg has the - eigth gen fighter .Everything is possible if (Money) available for such development.
thats why saudi arabia - lead in space reaserch
that why - UAE - has stronger defense than pakistan.
thats why russia being one of the poorest country cant even make a firecracker let alone a - cruise missile.
money is surely a criteria but its not all - its a very small aspect - the rearch and development - history , the will of people , support of nation and mental ability are way more important.
you should know it more than anybody - that pakistan being a poor country still hold an edge over many other in science and technology - smiler to india.
