Sommario/riassunto |
|
Opinions of the Presidency of George W. Bush and his perceived legacy seem to exist only at the extremes. From the contentious outcome of the 2000 election, to the attacks on September 11, to the ongoing War in Iraq and Afghanistan, to the efforts to transform major domestic policies, and culminating with the financial crisis of 2008, it is little wonder that the name George W. Bush tends not to evoke lukewarm opinion. During his time in office, Bush obtained the highest approval ratings of ... |
