Can't we or don't want to impose effective sanctions on Russia?

Russia continues to effectively bypass the sanctions imposed on it. It exploits existing legal loopholes and 3rd countries and cryptocurrencies for this purpose. Her “shadow fleet” supplies oil, bringing in revenue. Microprocessors and aircraft parts are imported or smuggled. European companies, and especially German ones, export to Russia, despite the ban, components for its military sector - from dense goods vehicles to night imagination gogs to steel structures, and its soldiers walk around in shoes made through supplies of glue and leather. The Russian economy is staying afloat through heightened economical relations with Asian and mediate east states. Dual-use goods, passing in transit through its territory, are besides stolen.
