Ukrainians defied pressure from Moscow with a national show of flag-waving unity Wednesday, while the US warned that Russia had added as many as 7,000 troops near Ukraine's borders despite Kremlin declarations that forces were being pulled back from the region. While a feared Russian invasion of Ukraine did not materialize as feared, the United States and its allies maintained that the threat is still strong, with Europe's security and economic stability in the balance. Russia has massed more than 150,000 troops east, north and south of Ukraine, according to Western estimates. Russian President Vladimir Putin has signaled that he wants a peaceful path out of the crisis, and US President Joe Biden promised that the US would continue to give diplomacy "every chance," but he struck a sceptical tone about Moscow's intentions.
