In the history of borders in this barbarous region, 80 years is nothing.
The Treaties of Lausanne and Sevres do not serve the interests of the United States and should be abrogated.
First, the treaty of Sevres was superceded by Lausanne, so your wish has come true in that regard.
Second, the US is not even a signatory to the Treaty of Lausanne. The signatories were:
HIS MAJESTY THE KING OF THE UNITED KINGDOM OF GREAT BRITAIN AND IRELAND AND OF THE BRITISH DOMINIONS BEYOND THE SEAS, EMPEROR OF INDIA:
The Right Honourable Sir Horace George Montagu Rumbold, Baronet, G.C.M.G., High Commissioner at Constantinople;THE PRESIDENT OF THE FRENCH REPUBLIC:
General Maurice Pelle, Ambassador of France, High Com missioner of the Republic in the East, Grand Officer of the National Order of the Legion of Honour;HIS MAJESTY THE KING OF ITALY:
The Honourable Marquis Camillo Garroni, Senator of the Kingdom, Ambassador of Italy, High Commissioner at Constantinople, Grand Cross of the Orders of Saints Maurice and Lazarus, and of the Crown of Italy;
M. Giulio Cesare Montagna, Envoy Extraordinary and Minister Plenipotentiary at Athens, Commander of the Orders of Saints Maurice and Lazarus, Grand Officer of the Crown of Italy;HIS MAJESTY THE EMPEROR OF JAPAN:
Mr. Kentaro Otchiai, Jusammi, First Class of the Order of the Rising Sun, Ambassador Extraordinary and Plenipotentiary at Rome;HIS MAJESTY THE KING OF THE HELLENES:

Dr. Miloutine Yovanovitch, Envoy Extraordinary and Minister Plenipotentiary at Berne;THE GOVERNMENT OF THE GRAND NATIONAL ASSEMBLY OF TURKEY:

So, how is the US going to abrogate something she is not a party to in the first place?
