Sounds like OP washed out after the instrument phase, which would lead me to believe that it was the advanced contact and/or formation phase (or whatever they call it these days) that got him. Fortunately, you don't have to be competent in acro or formation flying to be an airline pilot, duh! I don't mean to knock on the airline pilot profession (I'm one of them), but you don't have to be Chuck Yeager to fly a modern airliner. As long as the OP can make it through the ratings and training programs, I can't see why he can't be an airline pilot, Mike! I've flown with a few ex-military pilots who can't fly and think at the same time, even with the autopilot engaged. Apparently, the weed out process hasn't been perfected.

In regards to international students, not all countries that participate have limitless funding and/or "pride issues". It all depends on their culture and $$$. If you are talking about middle eastern countries, yeah, they have the "pride issue" and the $$$ to keep their students in the pipeline. I know several Saudis and Kuwaitis who washed back an entire year because they could not put a T-38 on the ground safely. After millions $$$, they finally caught on and were able to solo, and eventually graduate. I made sure I wasn't on the schedule to fly that day. Other European countries and Southeast Asian countries do not have the extra millions $$$ to spend (don't have big "pride" issues either), so they'll cut their losses just like Uncle Sam would. The difference between them and the middle eastern countries is that their students are well prepared before they are sent to SUPT. I find that many of the middle eastern country students are from the royal family and/or have ties to them.
I had a couple of Singapore students and they were super sharp. They also had over 100 hours in a Alpha Jet. One of them told me that they started with a 1,000 candidate and only 100 finished. Of the 100, only a dozen were sent to the states to attend SUPT. How about ENJJPT? Not all foreign students make it through that program. When was the last time you've heard a international student pilot get beheaded or flogged for washing out? Times are changing.
