Given that the defence alliance was never used under the pact and that the main signatories between Europe and Asia were distant from each other and that cooperation between the European and Asian signatories was limited, the impact of the pact was limited. Historian Paul W. Schroeder described it as a rapid decline from an “important position at the end of 1940 to a purely nominal existence at the end of 1941″ and as “practically operational” until December 1941.  However, the pact proved useful in convincing the American people that Japan was acting in alliance with Germany.  The accusation that the pact was part of efforts to coordinate aggression and dominate the world was also part of the trial of Nazi leaders at Nuremberg.  Similarly, the Tokyo war crimes trials also focused on the creation of mixed technical commissions between Germany, Japan, and Italy as evidence that the Covenant began to function shortly after it was signed, showing mutual support in aggression under the Covenant, even though these commissions never really worked.  The Tripartite Pact was primarily directed against the United States. Its practical impact was limited because the Italian-German and Japanese operating rooms were located at opposite ends of the world and the conventional high powers had different strategic interests. As such, the Axis has always been a loose alliance.  Its defense clauses were never invoked, and the signing of the agreement did not oblige its signatories to wage a common war in itself.  The Tripartite Pact is signed by Germany, Italy and Japan In June 1934, Hitler and Mussolini meet for the first time in Venice. The meeting was not consensual. Hitler demanded that Mussolini compromise on Austria by pressuring Dollfuss to appoint Austrian Nazis to his cabinet, after which Mussolini categorically rejected the request.
In response, Hitler promised that he would accept Austria`s independence for the time being, saying that Germany could not afford to provoke Italy because of internal tensions in Germany (concerning parts of the Nazi SA that Hitler would soon kill on the night of the long knives).  Galeazzo Ciano told the press that the two leaders had reached a “gentleman`s agreement” to avoid interference in Austria.  The Tripartite Pact was the culmination of a series of agreements between Germany, Japan and Italy. On 25 October 1936, Germany and Italy conclude a cooperation agreement on the Rome-Berlin axis. A month later, Japan joined the so-called Axis powers by signing (with Germany) the Anti-Comintern Pact, an anti-communist agreement directed mainly against the Soviet Union; Italy signed in 1937. However, this treaty was broken with the German-Soviet Non-Aggression Pact of August 23, 1939, which paved the way for Germany`s invasion of Poland the following week and at the beginning of World War II. The original agreement of the document also concerned Yugoslavia`s acceptance of the free movement of German troops throughout the country; This was not satisfactory for the leader and led to the invasion of Yugoslavia. Thailand fought the Franco-Thai War from October 1940 to May 1941 to retake territory from French`Indochina.
Japanese troops invaded Thai territory an hour and a half before the attack on Pearl Harbor (because of the international date line, the local time was the morning of December 8, 1941). Only a few hours after the invasion, Field Marshal Phibunsongkhram ordered an end to resistance to the Japanese. On December 21, 1941, a military alliance with Japan was signed, and on January 25, 1942, Sang Phathanothai read Thailand`s official declaration of war in the United Kingdom and the United States on the radio. Thailand`s ambassador to the United States, Mom Rajawongse Seni Pramoj, did not hand over his copy of the declaration of war. Although the British retaliated by declaring war on Thailand and considering it a hostile country, the United States did not. The Tripartite Pact, also known as the Tripartite Pact, Axis Pact, Tripartite Pact or Tripartite Treaty, was a pact signed in Berlin on September 27, 1940 that founded the Axis powers of World War II. The pact was signed by representatives of Nazi Germany (Adolf Hitler), Fascist Italy (Foreign Minister Galeazzo Ciano) and Imperial Japan (Japanese Ambassador to Germany Saburō Kurusu). Political talks aimed at clarifying Russia`s position in the immediate future have begun.
Whatever the outcome of these talks, all previously ordered preparations for the East must be continued.

Adolf Hitler The Spanish state of Caudillo Francisco Franco provided moral, economic and military support to the Axis powers, while nominally maintaining neutrality. Franco described Spain as a member of the Axis and signed the Anti-Comintern Pact with Hitler and Mussolini in 1941. In a communiqué with Germany on 26 May 1942, Franco declared that Portugal should be annexed by Spain.  In this context, officials from Germany, Italy, and Japan met in Berlin in September 1940 to draft the Tripartite Pact. In particular, he called on the signatories to “support each other by all political, economic and military means” if one of them is attacked by “a power that is not currently involved in the European war or the Sino-Japanese conflict”. Such a formulation excluded, in particular, the Soviet Union, which was already involved in both wars, and was therefore seen as a warning to the United States against entering World War II. The pact was signed by Joachim von Ribbentrop (Germany), Galeazzo Ciano (Italy) and Kurusu Saburo (Japan). Several other European countries – some of which had been forced – were subsequently signatories. The axis arose from the diplomatic efforts of Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. .
