Austria has denied the United States permission to use its airspace for military operations related to the war with Iran, citing the country’s long‑standing policy of neutrality, according to statements reported Thursday by Austrian public broadcaster ORF.
Who knows. Could be pressure from Iran. “Block your airspace and we’ll let some of your ships pass…” or something.
Either way. Good for everyone doing it regardless of the reason.
I don’t think Austria has any oil tankers.
Extrapolate. The ships that deliver to the refineries that supply your energy.
