First Freedom of the Air: the right or privilege, in respect of scheduled international air services, granted by one State to another State or States to fly across its territory without landing (also known as a First Freedom Right).
Accurate. Country of Origin is basis in this case which is Greece. Adequate response would be to indefinitely bar all Belarusian originating flights from traveling through any signatory's airspace.
However, this most likely only furthers the goals of the current Belarusian administration for the population there. Enforced strictly, to include diplomatic flights, it may cause measurable change.
Cannot be allowed to stand by whom? Everyone else is too busy silencing proper journalists, in what world are we where you actually think there is a country that stands for 'free speech'? Speech that's against the status quo gets silenced, just cus you buy everything the MSM sells doesn't mean the rest of the world has to. People need to travel(or explore different perspectives if possible) more or at least stop spreading ignorance.
