But you need one government that can lock everything down and control all borders easily. Controlling all borders would only have been viable on a EU level, but a unified strategy was and still is impossible.
Hermetically closing borders would be very hard for Czech Republic (with strong economic and personal ties to the neighboring countries). There was political will to go for zero covid strategy anyways.
If I was allowed to go for some dream solution it would be coordinated strategy on EU (or Schengen) level.
