Why is Egypt so wary of getting involved in Yemen’s conflict?

The deployment of thousands of Egyptian troops to Yemen from 1962, backing republicans against Saudi-supported royalists, remains a powerful memory in Egypt. Although the republicans won, Egypt withdrew after its 1967 war with Israel and heavy losses in Yemen. Recent remarks by President Abdel Fattah el-Sisi about a possible military deployment revived concerns, but he said it would focus on defending Saudi Arabia and would not directly attack the Houthis. Foreign Minister Badr Abdelatty called for a political solution.
