Input: Consider Input: We're not bluffing, the Obama administration told Afghanistan on Tuesday in announcing for the first time it has started planning for the possible withdrawal of all U.S. troops by the end of the year if no security agreement is signed. Statements by the White House and Defense Secretary Chuck Hagel showed President Barack Obama's impatience with Afghanistan President Hamid Karzai's refusal to sign the agreement that would keep several thousand American troops in the country after combat operations conclude this year. In a phone call with Karzai on Tuesday to discuss upcoming elections for a new Afghan leader, Obama made clear that time was running out to properly plan for keeping any U.S. forces in the country beyond 2014, the White House said.President Obama calls Afghan leader to discuss security agreementObama orders planning for bringing home all U.S. troops at the end of 2014Afghan President Karzai refuses to sign a deal to keep some troops thereThe White House says an agreement could happen after Karzai leaves office in April

Input: Consider Input: (CNN) More Americans than at any time in Barack Obama's presidency now say that things in the United States are going well, a sharp uptick in positive views and the best reviews of the country's trajectory since January 2007, according to the latest CNN/ORC poll. Overall, 54% say things in the country today are going well, 46% badly. That's a reversal from late July when 54% said things were going poorly and 46% said they were positive. The improvement in impressions of the country's path stems largely from shifts among Democrats and independents. Among Democrats, 85% say things are going well, up from 76% in late July. Among independents, 51% now say things are going well, up 9 points since this summer. There's been no significant shift, however, among Republicans: 21% now say things are going well, not significantly different from the 17% who said so in July.54% to 46% say things in the country are going well compared to badlyThat's a reversal from late July
