The reports described above are almost all violations of actual territorial airspace, not ADIZs, including the recent Russian incursion into Swedish airspace. Most countries don't have an ADIZ at all, including most of Europe. In fact ADIZs have no legal foundation, and countries may not shoot down aircraft within them outside of wartime as they're still international airspace. While Russia routinely violates the national airspace (not ADIZs) of European countries there are few to no similar cases of European (or even American) military aircraft doing the same to Russian airspace in the past 30 years. This is a very asymmetric escalation & intimidation.
