“Foreign influence is truly the Grecian horse to a republic. We cannot be too careful to exclude its influence.”

It was foreign influence that brought the de jure States united republic into being. It was the foreign socialist influence that brought a standing army (policing departments) to enforce tyranny. A lot of truth there, just not always.

He may have meant Trojan Horse. Hamilton was a bit prissy.

Valerie Jarrett backed by George Soros foreign influence enough?

Amen!

To paraphrase George Washington's Farewell Address: "Avoid foreign entanglements."

Did we listen?

"To cherish peace and friendly intercourse with all nations having correspondent dispositions; to maintain sincere neutrality toward belligerent nations; to prefer in all cases amicable discussion and reasonable accommodation of differences to a decision of them by an appeal to arms; to exclude foreign intrigues and foreign partialities, so degrading to all countries and so baneful to free ones; to foster a spirit of independence too just to invade the rights of others, too proud to surrender our own, too liberal to indulge unworthy prejudices ourselves and too elevated not to look down upon them in others...." James Madison
Madison's Inaugural Address - The American Presidency Project
March 4, 1809

"The great rule of conduct for us in regard to foreign nations is, in extending our commercial relations to have with them as little political connection as possible.... Trust in temporary alliances for extraordinary emergencies... steer clear of permanent alliances with any portion of the foreign world." (President George Washington, Farewell Address, 1797)

"My policy has been, and will continue to be, while I have the honor to remain in the administration of the government, to be upon friendly terms with, but independent of, all the nations of the earth. To share in the broils of none. To fulfil our own engagements. To supply the wants, and be carriers for them all: Being thoroughly convinced that it is our policy and interest to do so." -- George Washington
(1732-1799) Founding Father, 1st US President, 'Father of the Country' - Source: 1795 - letter to Gouverneur Morris, ref: Washington's Maxims, 54.

"Honest friendship with all nations, entangling alliances with none," (President Thomas Jefferson, Inaugural Address, 1801)

George Washington: "The constitution vests the power of declaring war in Congress; therefore no offensive expedition of importance can be undertaken until after they shall have deliberated upon the subject and authorized such a measure." (1793.)

Not shooting the messenger here -- Aaron Burr saw to that. Hamilton ought know, he was responsible for allowing British and European financial powers to hijack the US Treasury and ultimately the monetary system itself -- we have not been able to get out from under their yoke ever since.

Heterogeneity is required for survival.

Is today's illegal immigration the newer Grecian horse?
