During the NATO summit in Bucharest in April 2008, American president George W. Bush lobbied for offering a Membership Action Plan  to Georgia and Ukraine. However, Germany and France said that offering MAP to Ukraine and Georgia would be "an unnecessary offence" to Russia. NATO stated that Ukraine and Georgia would become members of the alliance and pledged to review the applications for MAP in December 2008. Russian President Vladimir Putin was in Bucharest during the summit. At the end of the summit on 4 April, Putin said that expansion of NATO to Russia's borders "would be taken in Russia as a direct threat to the security of our country". After the Bucharest summit, Russia became more aggressive and began to actively prepare for the invasion of Georgia. Chief of the General Staff of the Russian Armed Forces Yuri Baluyevsky said on 11 April that Russia would take "steps of a different nature" in addition to military action to prevent NATO membership of former Soviet republics. General Baluyevsky admitted in 2012 that when the decision to attack Georgia was taken by President Putin before Dmitry Medvedev assumed the office of president of Russia in May 2008, a military action was planned and explicit orders were issued in advance before August 2008. Russia aimed to stop Georgia's accession to NATO and also to bring about a "regime change".

Mount Vesuvius has erupted many times. The famous eruption in AD 79 was preceded by numerous others in prehistory, including at least three significantly larger ones, the best known being the Avellino eruption around 1800 BC which engulfed several Bronze Age settlements. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, possibly in 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500. The volcano erupted again in 1631, six times in the 18th century (including 1779 and 1794), eight times in the 19th century (notably in 1872), and in 1906, 1929 and 1944. There have been no eruptions since 1944, and none of the eruptions after AD 79 were as large or destructive as the Pompeian one. Vesuvius entered a new phase in December 1631, when a major eruption buried many villages under lava flows, killing around 3,000 people. Torrents of lahar were also created, adding to the devastation. Activity thereafter became almost continuous, with relatively severe eruptions occurring in 1660, 1682, 1694, 1698, 1707, 1737, 1760, 1767, 1779, 1794, 1822, 1834, 1839, 1850, 1855, 1861, 1868, 1872, 1906, 1926, 1929, and 1944.

When did an eruption happen five years after the 1850 severe eruption but 21 years before that one?

Kabuls population is estimated to have been about 10,000 in 1700, 65,000 by 1878, and 120,000 by 1940. More recently, the population was around 500,000 in 1979, whilst another source claims 337,715 as of 1976. This figure rose to about 1.5 million by 1988, before dramatically dropping in the 1990s. Kabul became one of the fastest growing cities in the world, with its population growing fourfold from 2001 to 2014. This was partly due to the return of refugees after the fall of the Taliban regime, and partly due to Afghans moving from other provinces mainly due to war between Taliban insurgents and Afghan government forces in their native areas as well as looking for labor. This resulting rapid urbanization mean that many residents today live in informal settlements. Shanty mud-brick homes on the mountainsides and steep hills have been built by them and these are usually poverty-stricken, not connected to the water and electricity grid. Although the settlements are illegal, they have been tolerated by authorities. In 2017 Kabul Municipality started a project to paint the homes in these settlements in bright colors in an effort to "cheer up" residents.

How many years after one source claimed the population of Kabuls was 337,715 in 1976, did it ride to about 1.5 million?
