The strongest lobbies promoting foreign interests are driven by cohesive ethnic population groups in the United States, such as Armenia, China, Greece, India, Israel, Taiwan, Ukraine, and, historically, Ireland. Even countries that have strong bilateral relations with the United States, such as Australia, Japan, and Norway, need lobbyists as well as embassies. Lobbyists can operate within the system in ways that experienced diplomats cannot. A lobbying group can identify with a domestic ethnic bloc even though it is paid by a foreign government.
