Narrative:

Today I was a party to a pilot deviation which turned into an operational deviation. I had these two jets going to fort lauderdale. Aircraft X was following aircraft Y about 20 miles behind and capable of going about 200 knots faster. Aircraft Y was a foreign aircraft/pilot and after repeating my control instructions several times and having to south left O west left Y and phonetically spell out each clearance; realized that this plane was special and that this plane required special attention. Both jets were to cross jingl at 8;000 per LOA with miami approach; so I apreqed 6;000 for aircraft Y and lifted the speed restriction on aircraft X so that both aircraft could perform to their own capabilities. I issued the 6;000 crossing restriction to aircraft Y a couple of times until I was satisfied with the read back and convinced that the pilot might actually comply with the restriction; waited for mia approach to take the hand off and then shipped the aircraft to approach. I then watched as aircraft Y failed to make the crossing restriction; at which point I stopped aircraft X 1;000 ft above. I did not have time to call the effected approach controller and left aircraft X safely above aircraft Y at 9;000; still within the confines of the receiving controller's airspace; just 1;000FT above LOA; and shipped him to approach. The aircraft had a pilot deviation and as a result. I sent the commercial jet into approach airspace 1;000 above LOA. Recommendation; anticipating that this would probably happen; I should have vectored the alphabet aircraft out of the way; let the commercial jet go first; and then focused all of my attention on the foreign aircraft.
