How can the West stop the Russian missile strikes?

Suddenly, just arming the Ukrainians to fight and defend against the Russians doesn't seem enough. Whatever the Ukrainian military can do to shoot down some of the missiles, rockets and artillery shells pouring onto the country from a long way off, they keep on coming. The Ministry of Defence in London says Moscow is running out of missiles but tell that to the Ukrainian people. They have noticed no let-up in the constant strikes that are destroying their homes, power stations, water plants and railways. Nato, especially the US, has supplied billions of dollars worth of equipment from air-defence systems to winter clothing to help the Kyiv government confront Putin's invasion force but the missile and artillery assaults are never-ending. Can the West do more to stop this destruction? I know that Biden and co are desperately worried about doing anything that might cause a full-scale war between Russian and Nato because of the risk of it going nuclear. But Putin, as I wrote yesterday, is intent on destroying Ukraine's total infrastructure. And he will keep going until Ukraine begs for mercy. Whatever the MoD says in London about Moscow running out of stocks, Russia must have enough to terrorise Ukraine throughout the winter. So should Nato finally, at last, intervene and if it does, what could the alliance do to stop Putin's attempted annihilation of a country and its people? I believe the answer lies in helping Ukraine to carry out a series of spectacular attacks against the Russians which will so shock Putin that he will be forced by his own people to end the war. The US should provide all the intelligence and much longer-range missiles and artillery for Ukraine to go on the offensive with strikes on every military site in Crimea and destroy Russia's ability to wage war from Crimea. At the same time, the same intelligence and weapons should be provided for Ukraine to destroy every warship of the Russian Black Sea Fleet hiding in port at Sevastopol. That might make Putin halt in his tracks. There would be huge risks but the destruction of Ukraine by a vengeful Russian leader can no longer be allowed to continue.
