Hmm, maybe explain how exporting a bunch and then stopping could possibly stop reverse engineering. These machines are also available from the second hand market. I mean, your conclusion isn't wrong, that ASML is going to lose much of the market share in the long run anyway just because it's always a threat. But still Ericsson and Nokia used to get a portion of the Chinese market until Europe turned. The businesses, whether telecoms or fabs would always prefer more competition among their suppliers, if nationalism hadn't got in the way.
