You're mixing up the propaganda phrases, that's Russia's stance in Ukraine. Trump's is this is "an excursion", totally different things.
He didn't call it a special one though.
"Special operation"? Check. "$EnemyCapital in 3 days"? Check. "We haven't even started yet"? Check. "Goodwill gestures"? Check.
(It's actually a common joke on the Russian Internet. So common, in fact, that it has already stopped being funny.)
