There are several sources all over the Internet. Pick the one that suits you best. We defeated Saddam. Russia has not defeated anyone. They've been bogged down in this clusterfuck for over a year. Ukraine hasn't needed an air force. They're too busy shooting down Russia's.
I don't need sources that are mostly wrong. I got professional training on this thanks to the US Army.
Saddam defeated Iran in the Spring and Summer of 88 with five successive combined arms operations using Russian equipment and doctrine.
He took Kuwait and could have taken Saudi Arabia.
Egypt took and crossed the Suez in 1973 and very nearly took all of Israel.
Russia successfully invaded Afghanistan in 1979.
Russia successfully kicked the West out of a number of countries by supporting leftist revolutionaries. Cuba, Rhodesia, and Nicaragua come to mind.
We nearly lost the Korean War. Twice. Thank God for General Smith's deep expertise.
Russia directly built the NORK military and trained them.
And Greece very nearly fell in the 50s.
We lost Vietnam and we just got our butts kicked out of Afghanistan.
China is an adversary now. China builds and deploys more hulls in the Pacific each year than we do in five and they are building 1000 C17 clones which can be used only for expeditionary aggression.
Explain to me how we are so awesome.
Everything comes down to logistics including manpower and then strategy. Realistic planning and execution.
Explain to me how our strategy today NOW will end the war in the Ukraine in our favor. It can't. We don't even have a VII Corps sized force in Europe any more. No one does. We don't have deep war stocks in Europe anymore nor the means to even build them up - for the next two years.
Nor does Ukraine. And they never will.
One liners are all you have. Not sane realistic appraisals.
