Rubbish they did not defeat Hezbollah they are still there. And yes a Hezbollah drone flew into an army mess hall and raised hell. There is little to be leaned from the Iran /Iraq war. The USSR was able to take Afghanistan and hold much more of it then the USA was, and that is with the USA arming the opposition. Russia is causing between 8 and 10:1 casualties in Ukraine. If Russia was that primitive Ukraine would be kicking ass as its NATO trained and equipped army with full access to Western intel would make a big difference. It does not.
The survival of a few is not victory, Hezbollah was defeated, it leadership obliterated, Syria lost. the Golan heights barrier is now augmented with Mount Hermon, the Syiran Druze are now allies
A few dozens, even a few hundred of dead soldiers is not defeat; it is expected in war
In any case the article is about conventional war, not some guerrilla resistance.
Today there is little to leaned from the Iran /Iraq war... Yes, but some Iraqui general in 1990 might had taken conclusions, like the Russian guy that wrote that article. The Iraquis drew conclusions from a war fought between 3rd world countries and try to apply them against the USA.. It didn't end well
The USSR took Afghanistan quickly, but that is my point, these were not "2 opposing sides closely matched "; on one side there was a super power, vastly more powerful that successor state Russia, on the other side a backward tribal confederation.
Russia started the war poorly led, trained, equipped, a 3rd world army, otherwise it would not had lost almost a million casualties
Ukraine is primitive too: a few patriot missile batteries, old NATO tanks, old NATO planes, javelin missiles and whatever leftover the Europeans can throw doesn't make it a NATO army.
Neither side has been capable of achieving air superiority. Both sides lacks the precision missiles needed to take down the enemy's air defense systems, so stalemate
against NATO that won't be the case. Against NATO, the entire Russian air force gets obliterated in the first day of the war. The only card Russia has in that scenario is nuclear threat
