Veto usage at UN

US UN veto record
"The United States did not exercise its first veto until 1970, on a resolution regarding Southern Rhodesia, which is present-day Zimbabwe.
Since then, it has used its veto 79 times, with more than 40 related to issues in the Middle East.
The majority have been resolutions that have criticised the Israeli government or failed to condemn armed Palestinian factions in the same language as that being used for Israel.
It used its last veto to block a resolution that would term Israeli settlement activity in Palestinian territory "illegal" and demand a halt to all such actions.
Susan Rice, the US ambassador to the UN, said her country "reject[ed] in the strongest terms the legitimacy of continued Israeli settlement activity", but the resolution "risk[ed] hardening the positions of both sides" and moving them away from negotiations."

UK – UN veto record
The United Kingdom has used its veto 31 times; the first in 1956 when it joined France in opposing a resolution ordering Israel to withdraw from Egypt.
Its most recent veto was in 1989, when it joined the United States and France in rejecting a resolution that criticised the US military intervention in Panama.
London tends to use its veto in conjunction with other countries, usually France and the US, although it has used a unilateral veto on seven occasions.
