To recognize an insurgent as a belligerent is not to recognize him as fully the equal of the government from which he secedes.
James Blaine
The Public Record
James Gillespie Blaine was an American statesman and Republican politician who represented Maine in the United States House of Representatives from 1863 to 1876, served as Speaker of the House from 1869 to 1875, and was a United States senator from 1876 to 1881. He served twice as Secretary of State, under presidents James A. Garfield and Chester A. Arthur in 1881, and under Benjamin Harrison from 1889 to 1892. He sought the Republican presidential nomination in 1876 and 1880, and received the nomination in 1884, narrowly losing the general election to Democratic nominee Grover Cleveland. Blaine was a prominent figure in the moderate faction of the Republican Party, known as the "Half-Breeds".
Its application to the case of insurgents against an established and recognized government is later, involves other and in some respects different considerations, and cannot even now be regarded as settled.
In its primary and simple application, the law of belligerency referred to two or more belligerents, equally independent.
