Ezekiel 23:28

"For thus saith the Lord Jehovah; Behold, I will deliver thee into the hand of them whom thou hatest, into the hand of them from whom thy soul is alienated; and they shall deal with thee in hatred, and shall take away all thy labor, and shall leave thee naked and bare; and the nakedness of thy whoredoms shall be uncovered, both thy lewdness and thy whoredoms. These things shall be done unto thee, for thou hast played the harlot after the nations, and because thou art polluted with their idols. Thou hast walked in the way of thy sister; therefore will I give her cup into thy hand."

"All of these things shall be done unto thee, for thou hast just played the harlot after the nations ..." (Ezekiel 23:30). The complete understanding of what God meant in this chapter is here cleared up. "The allegorical picture-language is omitted. Not lovers, but nations are referred to, with whom Israel has played the whore."[22] But in the very same verse the second reason for Judah's punishment was given. Let it be remembered that this is in addition to the first reason: "And because thou art polluted with their idols"! So, it was actually whoredom, after all, namely, shameless indulgence in the wholesale immorality of the religious licentious of the pagan idols that was also a vital element in precipitating the terrible punishment that fell upon the people of God. This fact makes the meaning and fully justifies the repulsive terminology employed in the presentation of this remarkable allegory.

To speak of Judah's sin here as "nothing more than the seeking of political alliances" is to miss the point altogether.
