question: Increased attention to conventional strength complemented these special forces preparations. In this instance he called up reserves and also proceeded to expand the regular armed forces. Whereas active duty strength had declined from approximately 3,555,000 to 2,483,000 between 1953 (the end of the Korean War) and 1961, it increased to nearly 2,808,000 by June 30, 1962. Then the forces leveled off at around 2,700,000 until the Vietnam military buildup began in 1965, reaching a peak of nearly 3,550,000 by mid-1968, just after McNamara left office.
Answer this question: During which wars was the number of active duty people approximately 3,555,000?

question: Growth continued in the first years of the EU membership. The credit portion of the Financial crisis of 2007-2010 did not affect the Czech Republic much, mostly due to its stable banking sector which has learned its lessons during a smaller crisis in the late 1990s and became much more cautious. As a fraction of the GDP, the Czech public debt is among the smallest ones in Central and Eastern Europe. Moreover, unlike many other post-communist countries, an overwhelming majority of the household debt - over 99% - is denominated in the local Czech currency. That's why the country wasn't affected by the shrunken money supply in the U.S. dollars. However, as a large exporter, the economy was sensitive to the decrease of the demand in Germany and other trading partners. In the middle of 2009, the annual drop of the GDP for 2009 was estimated around 3% or 4.3%, a relatively modest decrease. The impact of the economic crisis may have been limited by the existence of the national currency that temporarily weakened in H1 of 2009, simplifying the life of the exporters.
Answer this question: How many years did the financial crisis last?
answer:
3
