Ukraine's sustained attacks on Russia's critical infrastructure have resulted in widespread fuel shortages, public disturbances, and a deteriorating economy, prompting allies of President Vladimir Putin to reportedly urge him to consider drastic measures. These battlefield setbacks have fueled speculation that hardliners within the Kremlin are lobbying for the deployment of nuclear weapons.

Experts suggest that the potential loss of Crimea, a territory with significant symbolic importance to Putin, could serve as a tipping point for such an escalation. Ukraine's forces have targeted fuel logistics, oil facilities, and military infrastructure, including repeated strikes on the Crimean Bridge, the primary supply route to the peninsula. Ukrainian President Volodymyr Zelensky has approved a drone campaign aimed at compelling Russia to end the war, with Kyiv reporting hits on 11 oil refineries and other key sites throughout June.

Putin has publicly acknowledged "a certain shortage" of fuel, admitting that Crimea had only "a few days' supply" remaining. These admissions coincide with mounting public criticism within Russia. Footage has emerged showing public brawls at petrol stations due to queues, and online searches for "how to siphon fuel" have reportedly surged. Influencers and war veterans have voiced concerns online about the economic impact and military conduct.

German Gref, head of the state-controlled Sberbank, has broken ranks to call for an end to hostilities, citing concerns from Russians about the war's economic toll, which includes falling wages, redundancies, and rising prices. A poll cited by one source indicates that 81% of Russians want the war to end. However, Putin's approval rating has reportedly seen a decline.

Amidst rising dissent, the Russian government has continued to censor critical voices. A military veteran's video accusing commanders of mistreating soldiers was met with his arrest. The situation echoes the past challenge posed by the Wagner mercenary group, whose leader was later killed in a plane crash.

Estimates from the Centre for Strategic and International Studies suggest substantial casualties on both sides, with Russian fatalities reportedly exceeding Ukrainian ones by a significant margin. Analysts observe that Ukraine has regained the initiative, shifting from a defensive posture to disrupting Russian supply lines and infrastructure.

Despite the internal pressures and battlefield difficulties, reports indicate that some Kremlin hardliners are increasingly advocating for the use of tactical nuclear weapons, targeting Ukrainian positions or even European nations supporting Kyiv. Russia's nuclear doctrine permits the use of atomic bombs in cases of an "existential threat" to the country. While some Western analysts dismiss such nuclear threats as rhetoric intended to deter support for Ukraine, the internal situation in Russia remains tense as Putin faces calls for peace alongside pressure for continued military action.
