A decision to reverse earlier decision & it is crying need of the day, so U-turn can be taken and is taken by Political leaders.
In practicality U-turn plays pivotal and vital role, it impacts while underscoring & emphasizing working strategy for any project, any plan and implementation thereof.
In America it is called "flip-flop" but in UK, Ireland, Pakistan it is termed as U-turn and in Australia and New Zealand known as Backflip.
It is a sudden real or apparent change of policy or opinion by a public official, sometimes while trying to claim that both positions are consistent with each other.
Often it will occur during the period prior to or following an election in order to maximize the candidate's popularity or formulating policy and procedure for the country.
Non-political use: Outside politics the use of U-turn is not termed as pejorative, uncomplimentary, disadvantageous, and unpleasant. It means in outside politics it is also appreciative
A scientist or mathematician can often obtain some experimental results or logical proofs which causes one to flip flop on a previously held belief.
The politician scrolling himself, considering merits and demerits & impending situations relevant to the plan in hand or while formulating policy and procedure, traveling around in a given situation and eventually arriving at a point where he sees the things appropriate and profitable then closes further scroll.
Rigidity & inflexibly goes against the plan, so U- turn gives an opportunity to look the thing in real perspective, afterthought and forethought & then decisive action.
It is a probability where the ball is rolled horizontally & vertically then a marginal points is achieved where the politician feels satisfied so it becomes only possible when U-turn as a tool is used.
It signifies ‘’as a change in someone opinion’’, to alternate back and forth between directly opposite opinion, ideas or decision.
It does not attract any repercussion or backlash or any bad feeling but a changed behavior in decision making.
The following situation similar to our politicians who change their ownership from party to another [whatever may the reason]
In the archives of The New York Times, which go back to 1851, the earliest unequivocal mention of "flip-flop" as a change in someone's opinion is in an October 23, 1890, report of a campaign speech in New York City. John W. Goff, candidate for district attorney, said of one of his opponents:
"I would like to hear Mr. Nicoll explain his great flip-flop, for three years ago, you know, as the Republican candidate for District Attorney, he bitterly denounced Tammany as a party run by bosses and in the interest of bossism.... Nicoll, who three years ago was denouncing Tammany, is its candidate to-day.
The term was also used in 1967, when a New York Times editorial and Times columnist Tom Wicker used it in commenting on different events. It was also in the 1976 election, when President Gerald Ford used the phrase against his opponent Jimmy Carter
In the 1988 U.S. presidential election, Michael Dukakis used the term against opponent Richard Gephardt, saying, "There's a flip-flopper over here" about Gephardt.
The term also was used extensively in the 2004 U.S. presidential election campaign. It was used by critics as a catch-phrase attack on John Kerry, claiming he was "flip-flopping" his stance on several issues, including the ongoing war in Iraq.
Famously, on March 16, 2004, during an appearance at Marshall University Kerry tried to explain his vote for an $87 billion supplemental appropriation for military operations in Iraq and Afghanistan by telling the crowd, "I actually did vote for the $87 billion, before I voted against it."
After the remark became controversial, he explained that he had supported an earlier Democratic measure that would have paid for the $87 billion in war funding by reducing Bush's tax cuts.
FactCheck stated that "Kerry has never wavered from his support for giving Bush authority to use force in Iraq, nor has he changed his position that he, as President, would not have gone to war without greater international support.
The term "U-turn" in the United Kingdom was famously applied to Edward Heath, the prime minister of the United Kingdom from 1970 to 1974.
Prior to the 1970 general election, the Conservative Party compiled a manifesto that highlighted free-market economic policies. Heath abandoned such policies when his government nationalised Rolls-Royce (hence the actual "U-turn").
The Conservative government was later attacked for such a move because nationalisation was seen (by the Thatcher era) as antithetical to Conservative beliefs.
This later led to one of Margaret Thatcher's most famous phrases: "you turn [U-turn] if you want to. The lady's not for turning". The Conservatives would adopt the free market under her.
The circumstances surrounding the flip-flop and its larger context can be crucial factors in whether or not a politician is hurt or helped more by a change in position. "Long hailed as a conservative champion, Ronald Reagan could shrug off his support of a tax increase in 1982 to curb the budget deficits his 1981 tax cut had exacerbated,"
According to an analysis of flip-flopping in The New York Times. "Long suspect on the Republican right, George [H. W.] Bush faced a crippling 1992 primary challenge after abandoning his 'no new taxes' campaign pledge in the White House.
Kerry's perceived equivocation on the Iraq war damaged his 2004 campaign, according to both Democratic and Republican political operatives. "It spoke to a pattern of calculation and indecisiveness that make him look like a weak commander in chief compared to [George W.] Bush", said Jonathan Prince, a strategist for 2008 presidential candidate John Edwards, Kerry's running mate in 2004.
In the 2008 primary season, Edwards simply stated that "I was wrong" when he had voted in the U.S. Senate to authorize the Iraq War. "Progressives loved it because it was taking responsibility, not abdicating it," according to Prince
United States commentator Jim Geraghty has written that politicians need to be allowed some leeway in changing their minds as the result of changing conditions. "I actually think that a candidate can even change his position in response to a changing political environment, as long as they're honest about it.
'The votes just aren't there, public support isn't there, so I have to put this proposal on the back burner for a while,' is a perfectly legitimate response to a difficult position."
