Since 1837 the United States have regarded Texas as an independent sovereignty as much as Mexico, and that trade and commerce with citizens of a government at war with Mexico can not on that account be regarded as an intercourse by which assistance and succor are given to Mexican rebels. The whole current of Mr. De Bocanegra's remarks runs in the same direction, as if the independence of Texas had not been acknowledged. It has been acknowledged; it was acknowledged in 1837 against the remonstrance and protest of Mexico, and most of the acts of any importance of which Mr. De Bocanegra complains flow necessarily from that recognition. He speaks of Texas as still being "an integral part of the territory of the Mexican Republic," but he can not but understand that the United States do not so regard it. The real complaint of Mexico, therefore, is in substance neither more nor less than a complaint against the recognition of Texan independence. It may be thought rather late to repeat that complaint, and not quite just to confine it to the United States to the exemption of England, France, and Belgium, unless the United States, having been the first to acknowledge the independence of Mexico herself, are to be blamed for setting an example for the recognition of that of Texas. And he added that-- The Constitution, public treaties, and the laws oblige the President to regard Texas as an independent state, and its territory as no part of the territory of Mexico.
