Upon the ambassadors' return, the Joseon court held serious discussions concerning Japan's invitation,Jones, Geo H., Vol. 23 No. 5, pp. 242–243 while Hwang Yun-gil reported conflicting estimates of Japanese military strength and intentions. They nonetheless pressed that a war was imminent. Kim Saung-il claimed that Hideyoshi's letter was nothing but a bluff. Moreover, the court, aware only that Japan was in turmoil with various clan armies fighting each other, substantially underrated the combined strength and abilities of many Japanese armies at the time. Some, including King Seonjo, argued that Ming should be informed about the dealings with Japan, as failure to do so could make Ming suspect Korea's allegiance, but the court finally concluded to wait further until the appropriate course of action became definite.Turnbull, Stephen. 2002, p. 38.
