It is frequently reported the Russian planes incur upon western airspace, and this presents challenges and demands on western air forces. Yesterday we had a report of Russian bombers “armed with nuclear warheads” reportedly entered Swedish airspace before being intercepted by fighter jets, and last month we had similar reports approaching UK airspace. Wikipedia says "In November 2014, the European Leadership Network reviewed 40 incidents involving Russia in a report titled Dangerous Brinkmanship, finding that they "add up to a highly disturbing picture of violations of national airspace, emergency scrambles, narrowly avoided midair collisions, close encounters at sea, simulated attack runs, and other dangerous actions happening on a regular basis over a very wide geographical area."
From a non-military viewpoint, it would seem that Russia would be much more vulnerable to this sort of tactic, having a very large border over which the west could conduct such operations, from Hungary over the Black sea area, from the Baltic states in the Northwest, through Scandinavia, Greenland and Alaska in the North and the Pacific in the East. I would presume that if Russia was intercepting western airplanes frequently over this wide area it would inevitably take away air capacity from Ukraine, thus supporting the effort to resist Russian occupation.
Why does the West not run such operations?
