evidence: Among the sites at risk in the Ukrainian capital are the nation’s most sacred Orthodox shrines, dating back nearly 1,000 years to the dawn of Christianity in the region. The sites, along with other landmark shrines in Kyiv, are religiously significant to both Ukrainian Orthodox and Russian Orthodox. They also stand as powerful symbols in the quarrel over whether the two groups are parts of a single people — as Russian President Vladimir Putin has claimed — or are distinct but related Slavic nations. [...] Whether Kyiv’s Orthodox shrines come under direct attack or receive collateral damage, such an action would be a "total refutation" of another of Putin’s claims — to be defending Orthodox Ukrainians loyal to Moscow’s patriarch, Lassin said.
