You do realize Kiev is only 90km from the border and Russia could easily rain FABs to demolish the city from bombers well within friendly airspace. The same is more true for Kharkov at only 30km from the border. The reason Russia doesn't do that is because it contributes nothing to the war.
(1)90km from border with Belarus, not with Russia. After failure of initial invasion, Belarus doesn't permit strikes from its area any longer.
(2)Kharkov is close indeed - and is being bombed occasionally. It, Zaporozhye and occasionally Dnepr are 3 cities which get occasional bombing.
But since early war, Russian bombing bandwidth is limited to production. Current high is just ~370 guided bombs per day. Add a few dozen other tactical PGMs, ok, we're at 400. Spread over these 3 cities and entire frontline.
US/IS applies them to identified valuable targets all over the country - a rich and unexhausted target list.
And USIS lost 3x F-15 over Iran and Iraq not counting the ones shot down by Kuwait, you think they'd be using JASSMs from B-52 if it can fly safely into Iran? The fact that USIS disavow, or in Israel's case literally has a Hanabal directive to kill their own captured soldiers is a phenonmon unique to USIS whose force are made up not of people but slaves, where they care more about saving face than protecting their people.
Iran is big. In some parts of Iran, they're bombing ~freely enough at this point - risk is manageable for tactical fighters.
In others - it still isn't, but overall rolling of air defenses is clearly in process.
US/IS didn't lose 3x F-15 over Iran; not a single one. Kuwait accident, while damaging, doesn't really add much threat to Iranian AD. As such, despite this case, loss rate remains ignorable.
The need to kill children and the belief you can win with terror bombing is an exclusively USIS concept, a concept they like to project to others. There is a reason all civilized countries with long lasting histories all converged on similiar moral codes, and there's a reason the people making up Israel has been kicked out of every civilizaed country for 2000 years and could never keep their own nation together for more than 80. Simply put the human world is just not comparable to USIS.
Winning with terror bombing, like it or not, was achieved many times in history.
And the so-called
civilized countries, as far as i can see, took mouthload of water about it and don't dare to produce a single sound. German prime minister was very open about his opinion on whom international law protection is for.
