Putin under pressure from hardliners to declare all-out war on Ukraine following Operation Spiderweb, Telegraph reports

Russian President Vladimir Putin is facing renewed pressure from hardliners to formally declare war on Ukraine, with critics inside the Kremlin warning what he calls his "special military operation" no longer goes far enough.
Anger intensified following Ukraine’s June 1 drone strike, dubbed Operation Spiderweb, which targeted four Russian air bases deep inside the country and reportedly damaged at least 20 Russian nuclear bombers. "Shock and outrage" is how one senior official described to the Telegraph the mood in the Kremlin, while another called the attack "a personal tragedy."

Russia has apparently redeployed dozens of long-range bombers to more remote bases within the country following the strike, Russian independent media outlet Agentstvo reported on June 11, citing OSINT analyst AviVector.
Despite the escalation, the Kremlin has so far avoided any dramatic shift in strategy. "This did not catalyse a political discussion or a change in the format of military operations," a former Kremlin official told the Telegraph. Another source close to the Russian Defense Ministry said, "Could the president declare war on Kyiv? Right now, unlikely. As cynical as it may sound, the leadership is satisfied with the current situation."
Hardliners argue that only a formal war declaration would permit true escalation—full-scale mobilization, regular missile strikes, and potentially the use of tactical nuclear weapons. One analyst told the Telegraph that a formal war declaration would give the Russian government sweeping authority to shift the country fully onto a wartime footing.
However, despite record levels of defense spending, the Kremlin has avoided taking that step—seeking instead to preserve the illusion of control and protect the broader population from the immediate impact of the war.
The Kremlin is projected to allocate 6.3 percent of its GDP to defense this year — the highest level since the Cold War — yet still far below what would typically indicate a country fully mobilized for war. By contrast, Ukraine spent 34 percent of its GDP on defense last year, while British military spending surpassed 50 percent of GDP during the Second World War.
"Mobilization undermines economic stability," said one current government employee. According to him, those in Putin’s inner circle have convinced the president that large-scale mobilization could trigger the collapse of the war effort. "And why is it needed now? We have Kalibr missiles, we have volunteers. Their resources are not yet exhausted," he was quoted as saying.
