Ukraine brings back conscription amid unrest in country’s east
“Ukraine’s acting President Aleksandr Turchinov has announced he is reinstating a military draft to help deal with the “deteriorating” situation in the country’s east and south.
The draft will call on all males between 18 and 25 years of age, who are not eligible for an exemption.
Turchinov’s office said in a statement on Thursday that the decision was made “given the deteriorating situation in the east and the south...the rising force of armed pro-Russian units and the taking of public administration buildings...which threaten territorial integrity.”

I hope you realize that Ukraine resorted to at least six ‘partial mobilizations’ during its failed campaign against the Donbas separatists in 2014-2015.
Are you prepared right now to assert that ‘at no time’ did Ukraine ever issue a mobilization that Zelenski was eligible for?
You might want to focus on the Poroschenko years as you do your research.
