Russian President Vladimir Putin's "special military operation” into Ukraine began on Feb. 24, with troops crossing the border from Belarus and Russia. Moscow's forces have since been met with “stiff resistance” from Ukrainians, according to U.S. officials.
Russian forces retreated last week from the Kyiv suburbs, leaving behind a trail of destruction. After graphic images emerged of civilians lying dead in the streets of Bucha, U.S. and European officials accused Russian troops of committing war crimes.

Ukraine intel chief says Russia plans a 'Korean scenario'
Russian President Vladimir Putin may be seeking to split Ukraine in two after failing to seize the capital, Kyiv, according to the head of Ukraine's defense intelligence agency.
Brig. Gen. Kyrylo Budanov said in a statement Sunday that Putin may now be pursuing a "Korean scenario" that would see Russian forces try to occupy the east and south of Ukraine since they no longer have the strength to "swallow the whole state."
"After the failures near Kyiv and the impossibility to overthrow the central government in Ukraine, Putin is already changing his main direction of operations -- to the south and east," Budanov said. "There are grounds to suggest that he is considering the Korean scenario for Ukraine. That is to attempt to lay down a new line of contact between the non-occupied and occupied regions of our country. In fact, it's an attempt to create in Ukraine a North and South Korea. Indeed, he definitely doesn’t have the strength to swallow the whole state."

Budanov said he believes Putin still wants to open a land corridor between the Moscow-annexed Crimean Peninsula and the other Russian-controlled regions in eastern Ukraine, which would mean the occupation of besieged Mariupol, a strategic port city in the southeast that has been under heavy Russian bombardment. But he said Ukraine's continued counterattacks as well as resistance by local people in the occupied areas were disrupting Putin's plans.
Budanov also predicted the start of guerrilla warfare that would make it impossible for Russia to hold territory.
"Soon the season of the total Ukrainian partisan safari will start," he said. "Then for the Russians will remain only one relevant scenario -- how to survive."
