<P0-S0> israel has one of the highest ratios of defense spending to gdp of all developed countries, only topped by oman and saudi arabia. <P0-S1> in 1984, for example, the country spent 24% of its gdp on defense. <P0-S2> by 2006, that figure had dropped to 7.3%. <P0-S3> israel is one of the world's largest arms exporters, and was ranked fourth in the world for weapons exports in 2007. the majority of israel's arms exports are unreported for security reasons. <P0-S4> since 1967, the united states has been a particularly notable foreign contributor of military aid to israel: the us is expected to provide the country with $3.15 billion per year from 2013 to 2018. israel is consistently rated low in the global peace index, ranking 148th out of 162 nations for peacefulness in 2015. <SEP> <P1-S0> During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). <P1-S1> The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). <P1-S2> It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). <P1-S3> The territory became the Eritrea Governorate within Italian East Africa in 1936. <P1-S4> Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. <P1-S5> Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution. <P1-S6> [citation needed] <SEP> <P2-S0> The Intergovernmental Panel on Climate Change (IPCC) is a scientific intergovernmental body under the auspices of the United Nations, set up at the request of member governments. <P2-S1> It was first established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and later endorsed by the United Nations General Assembly through Resolution 43/53. <P2-S2> Membership of the IPCC is open to all members of the WMO and UNEP. <P2-S3> The IPCC produces reports that support the United Nations Framework Convention on Climate Change (UNFCCC), which is the main international treaty on climate change. <P2-S4> The ultimate objective of the UNFCCC is to "stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic [i.e., human-induced] interference with the climate system". <P2-S5> IPCC reports cover "the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation." <SEP> <P3-S0> bunnies on the bayou is a 501(c)(3) organization and the name of its similarly-titled annual tradition among members of the lgbt community of houston, texas, in the united states. <P3-S1> according to its website, the organization's mission is to raise funds for "various charitable, educational and cultural programs that seek to improve the quality of life for individuals in the lgbt community and promotes education and awareness of individual human rights within greater houston area. <P3-S2> the fundraiser is one of houston's largest outdoor events and has been called the city's" largest annual outdoor cocktail party". <SEP> <P4-S0> As of 29 February 2016, 124 countries were contributing a total of 105,314 personnel in Peacekeeping Operations, with Ethiopia leading the tally (8,324), followed by India (7,695) and Bangladesh (7,525). <P4-S1> In June 2013. <P4-S2> Pakistan contributed the highest number overall with 8,186 personnel, followed by India (7,878), Bangladesh (7,799), Ethiopia (6,502), Rwanda (4,686), Nigeria (4,684), Nepal (4,495), Jordan (3,374), Ghana (2,859), and Egypt (2,750). <P4-S3> As of 28 February 2015, 120 countries were contributing a total of 104,928 personnel in Peacekeeping Operations, with Bangladesh leading the tally (9446). <P4-S4> As of March 2008, in addition to military and police personnel, 5,187 international civilian personnel, 2,031 UN Volunteers and 12,036 local civilian personnel worked in UN peacekeeping missions.
