Eastern European countries warned us, but western Europe, Germany in particular, but other western European countries too, assumed Russia was now a normal country we could just trade with. Under Yeltsin we might have been heading in that direction, but Chechnya should have been a warning. Putin's comment about "countries that don't matter" was a warning. Russia taking chunks out of Georgia should have been the alarm. We continued trading even after he took Crimea and Donbas. We have been way too naive.
