The attack on the Russian bomber planes has been called "Russia's Pearl Harbor" and has created great commotion among both Russian military bloggers and foreign media.
The attack risks escalating the conflict to a level that is seen as unacceptable from an American perspective, says Keith Kellogg, President Donald Trump's envoy for Ukraine and Russia.
When you attack an opponent's nuclear triad, it means that your risk level goes up because you do not know what the other side will do, he says.
A nuclear triad means that a country can launch nuclear weapons from land, sea, and air.
It's not about the damage to the bomber planes, it's the psychological impact it has, says Kellogg, who claims that the risk levels have reached new heights.
It shows that Ukraine can raise the risk level to a level that, for me, must be seen as unacceptable, he says.
