AI air force is almost completely beyond our control. We can tell the AI how important it is to protect resources and IC, but not to escort bombers or provide CAP for armies. Also the AI cheats on rebase range, which allows them to place aircraft almost anywhere.
Regarding diplo and joining the Axis this is well known but cutting back on DI doesn't help as Germany, Italy etc all gain DI every month and any country which is PA is *very* likely to join the Axis once Paris falls. One option is to edit the governments and make some of them Centrist instead of Paternal Autocrat.
Note: the same applies to the Allies. For example if Poland goes left in the 1936 elections it is almost certain that they will join the Allies as the UK invites them 4-6 times per year.
