Republicans are backing an aggressive policy toward Ukraine ...

The "vast majority of the Republican Party writ large, both in Congress and across the country, are totally behind the Ukrainians and urging the president to take these steps quicker, to be bolder," Senate Minority Leader Mitch McConnell said Sunday on "Face the Nation." "There's been a pretty dramatic division between the traditional post-WWII Republican view of our leadership in the world, which is the one I hold, and those who wanted to follow a policy that was more focused on retreating to thinking that somebody else would fill our role in the world if we didn't," Sen. Roy Blunt of Missouri told CBS News. Colin Dueck, a senior fellow at the American Enterprise Institute who wrote a book on post-WWII Republican foreign policy, told CBS News that even though Trump tapped into voters' frustrations with traditionally hawkish GOP views, party voters still maintained their support of NATO and opposition to Putin. He's a very intelligent actor, although I'd say he's been quite erratic in his approach to the Ukraine."While Republicans are rallying around a hard line against Russia, they aren't eager to criticize Trump for his past behavior towards Putin. But I will say, in my view, when the time came to really get tough, to sanction Nord Stream 2 for instance, he was there at the end to do the right thing to be tough on them," Hawley told CBS News when asked if he thought the previous president miscalculated Putin.
