The only way this changes is through a war, in which case domestic production will become a primary concern above all others. But the consequences aren’t worth the benefits, peace and global trade is by far the best outcome for everyone.
The threat of War is often good enough. Also we may not have another hot war, but it seems increasingly likely that we will see another cold war in the near future.
These were 'interventions'. When you can bomb somebody and but there is no credible thread that your own population can be bombed back then it's not really a war. Your population doesn't feel the 'heat' and will not accept any inconveniences of ramping back domestic production
